Because the skills and effort needed to market and sell your art to an audience are not equal to the skills and effort needed to produce good art [1].

I agree that there could be other complementary or better solutions compared to this scheme. But as long as the above premise is true, not every good artist will want or be able to sell well.

[1] However you define this. Supposedly, Van Gogh was a lousy salesman, but a good artist.
