There's neither right nor wrong, neither good nor bad about the existence of all kind of celebration day or event, where many people like as well as 'need' to be celebrating certain things at certain timing for specific reasons, where people 'need' the existence of certain celebration day or event that involve certain activities and interactions among human beings, to ignite and boost the sense of belonging, happiness, meaningfulness, achievement, connection and togetherness, while some people are not interested or don't need to be engaging in any kind of celebration day or event, with or without any specific reason.
Anyhow, the existence of funeral is something important for many people to be able to 'let go' those who are gone, not just physically, but more so, mentally and emotionally.
All kind of celebration day/event/ritual are being celebrated by human beings on different timing under different reasons, either hourly, daily, weekly, monthly, seasonally, annually, and so on.
Although certain celebration day/event/ritual existed under certain ancient cultural and spiritual belief, values and practice along with the beginning of human existence long before the era of commercialism, most of the celebration day/event that have been continuously popping up here and there, are indeed the by-products of commercialism, to boost business or sales, a.k.a. profits, income, or wealth, for somebody.
The local/regional and international/global economy is very much being powered by all kinds of celebration day/event/ritual. The more type of celebration event existing in the world, the better it is for all kind of business/job/opportunity.
The mental and emotional health of many people, and the relationship/connection between human beings are also very much being influenced by the existence of the many different type of cultural and spiritual celebration event that generate the 'intention' or 'obligation' for people to come together, from time to time.
Some celebration day/event/ritual can be without the need of related 'objects', 'feasts', 'activities' or 'travelling' which require certain amount of 'inevitable expenses', where people don't necessarily have to be spending any money at all to be appreciating or celebrating something, however, most celebration day/event/ritual or funeral are associated with certain amount of 'inevitable expenses', where it can be 'financially difficult' or 'non-affordable' for some people, and even 'embarrassing', 'regretting' or 'guilty' for certain people.
In the event of funeral, some people cannot 'afford' to organize a so called 'funeral' for their loved ones. More money are being spent after death than while living for some people. Some people are depriving themselves while living in order to be saving enough money for arranging their own funeral the way that they prefer, if they think and believe that they need to have particular type of funeral for themselves after death under certain belief, values and practice. Just like many other things, funeral as well as after death's weekly, monthly and yearly ongoing ritual is a big money making business.
Certain 'crimes' also happened to be more frequent before and during certain celebration day/event or even funeral, due to different type of 'desperation' as well as 'golden opportunity for crime' that exist along with the existence of certain celebration day/event/ritual, or funeral, in certain cultures.
Meanwhile, certain cultural or spiritual celebration day/event/ritual involved with 'the sacrifice/offer of something in order to receive/attain something in return'.
Regardless of the different differences that all human beings identifying with as 'who they are' and 'where they belonged', where different communities under different cultural and spiritual belief celebrate different kind of celebration event on different day, everyone under all kind of diversities seemed to be celebrating the universal 'New Year' everywhere in the world, where the beginning of a year represents 'a new beginning', or 'a fresh start', or 'new hopes' for most people, that ignites certain 'spark' or 'motivation' to be performing certain actions, or to be achieving something, such as 'new year resolution' or 'setting intention'. That is something that all diversities could be sharing and celebrating in common, putting aside all kind of difference/competition/discrimination.
Some minds would feel bored, joyless, meaningless, or lack of motivation, if without certain kind of celebration day/event/ritual, to have something well-worth to be celebrating about or deserve to be remembering about, to be engaging in certain activities, connections and interactions among human beings, from time to time.
Some minds might even be disturbed and offended by certain behavior or happening that appeared to be offensive or inauspicious towards certain celebration day/event/ritual, or funeral.
For the minds that have transcended all kind of names and forms, time, space and causation, that have realized selflessness and unconditional peace, that are free from the influence of ignorance and egoism, that are free from being conditioned by worldly passionate egoistic thinking, belief, values and practice, that are free from attachment, identification, desire of craving and aversion, judgment, comparison and expectation, would respect the existence of all kind of celebration day/event/ritual or funeral that have their own particular reason to be existing, however, these minds don't need to be engaging in or celebrating any specific celebration day/event/ritual to develop or boost the sense of belonging, happiness, meaningfulness, achievement, connection and togetherness, or to ignite the 'spark' or 'motivation' to be performing any kind of actions, or to 'sacrifice/offer something in order to receive/attain something in return', and they won't be disturbed or offended by any kind of behavior or happening that appeared to be offensive or inauspicious towards certain celebration day/event/ritual or funeral. They don't need 'funeral' to let go anyone physically, mentally and emotionally. They don't need 'togetherness' to appreciate all kind of relationship. They don't need 'specific timing', 'motivation', 'resolution' or 'setting intention' to be performing actions.
For these minds, every moment is nothing but the rise/beginning as well as the passing away/end of something. Every moment can be appreciated and/or celebrated yet there's nothing really need to be celebrated particularly on particular timing, transcending names and forms, time, space and causation, transcending the sense of goodness and badness, positiveness and negativeness, auspiciousness and inauspiciousness, deserving and undeserving, or meaningfulness and meaninglessness, void of boredom and loneliness.
