The difficulty is the biggest gains there are for singular goods which can't be copied at low cost.

Exquisitely designed piece of furniture = expensive copy

Well-written book = cheap copy, post-printing press

So we're not necessarily going to get "more access to better" (because we already had that), but just "cheaper".

Whether that hollows out entire markets or only cannibalizes the bottom of the market (low quality/cheap) remains to be seen.

I wouldn't want to be writing pulp/romance novels these days...
