"you can just support your favorite artist with $5"

sort of right? don't those $5 go to the LP? Artist gets 0.05

After price discovery the artist would need to "sell" the art by selling some or all of their 10M allocation to realize the price.

the greater market would need to accept creators (that includes devs) capturing value by selling some of their supply *whenever they want*. If the market doesn't accept that and the pressure is on the creator to hold forever then I don't see how this is necessarily better for artists because they're not really selling their art directly.
