If the world was more like disney imagines it to be then this could be possible. Or your parents are very rich and you don't have to pay rent etc. for yourself.

But in the end artists just like open source maintainers need money to pay their food and most of them can't afford to stop charging for their work.

I would love to do that but I can't afford it so I won't. If the system changes and the government gives every citizen 1k $ / month we can start this discussion again because I would really much appreciate to do things that I like without having to take money for my work.
