"Perhaps financial renumeration, while fair, isn't entirely necessary"
Is it that in your world, eating and paying the rent isn't necessary either?
'Many' creative people sounds like some programmers, which is somewhat small subset of all creatives. I'd be surprised if the majority of creative people — artists, writers, actors, and more — would happily go about saying that financial renumeration doesn't matter to them.
Destin, for example, puts a lot of effort into his videos and his work. Financial renumeration not being necessarily inevitably means Destin does something else for the majority of his time and does Smarter Ever Day less (if at all). This is almost certainly the same for every other artist out there. Sure — maybe all art isn't necessary. Maybe some of it is crap. But saying that being paid to be creative isn't necessarily means that you get very little art, if at all.
