Author Eric Flint makes the argument that it takes practice to get good at anything, including writing. If we want good quality creative work (books, music, etc.) then we have to create an environment where authors and musicians and other creative types can actually make a living while creating.
If they can't, it doesn't mean we won't have books or music, but it does mean we won't have *good* books or music. Plenty of "idiots who want to try" can and will step up to publish albums or books, but Sturgeon's Law will have to be revised to say "99.9% of everything is crap."
