Meanwhile I am playing a fan translation of a game that people made for free by people that will get nothing in return.
Bandai has never released the game in english because they don't think they'll make enough profit, despite fans urging them.
Passion and time is what creates things.
Profit hinders just as many things as it helps create.
There are two possibilities:
1) something is useful/necessary/desirable. if it's useful, people will make it regardless of profit because it inherently useful.
2) something is useless. if it's useless, people being motivated by profit to make it is a BAD thing.
Imo people to hype up the profit motive for art are acutely aware that artists fucking hate making a ton of the bland content that is made today (and they love consuming), and assume in a socialist society all art will be the deeper and more abstract stuff. The reality is probably we'll see more experimental stuff, but the majority will still be capeshit and dragonshit, just hopefully less soulless than at present.
Tl;dr: these people realize capitalism makes bad art but they just love bad art.
