Art community's are most always self managing, i would argue finding out who makes art is much more complicated.
>Giving housing forces people to live in certain places.
No one is forced to take free housing or being an artist, if you want something for free you have to play by rules.
>like the people don't know what they need
True, but why are people who are artist different from anyone else, that's my critique. Why is creating art more important then preserving art, being a scientist, a rare-potato-farmer, a retro-game-preserver...or a small town politician?
