I'm sorry you feel this way, but I do not think this is true for most creators. Too many of my friends have made wonderful things for the sake of it. And they're so self-effacing, they won't even mention these things.
Not judging you or your friends, but perhaps those who can do hobbies just for fun are in a position of privilege (enough time, money, financial and professional security) to be able to do so? The "hustle culture" is very real and is I think a side effect of the gig economy and the end of the 9-5 secure job with its strict boundaries of work and leisure time. If you still have that kind of job it's easier to have hobbies with no outcome than personal satisfaction (assuming no other "distractions" like small children). Most creators I happen to know are hustling, whether on Github or Wordpress or Etsy or IRL, either trying to make some money on the side or building a portfolio for their career or to help them score their next gig. Those that aren't are retired or have some secure, traditional 9-5.
