Someone once asked...
Someone answered with kindness...
Ime, all 'why's are built upon other people. The kinds of people are always different, but it's always people. I'd start trying to find a community you'd like to exist in, then contributing to it (the easier way to do that is to "keep showing up", ime, until you're undeniably a part of it). Working for/with the people there (which doesn't even have to be a physical place) is the strongest 'why' i can think of Note that it has to be people who are reasonable. You cannot use a hate-group as a community of this kind, because they *will* shed members on a whim. The people should be decent as a baseline (which is the majority, so it's fine)
