So I'm not exactly naive, but we should then discuss this instead of the red herring of copyright.
As a result of this, everything gets cheaper and more plentiful.
The counterargument I'd make to that would be the requirement that the human have creative skills, which might atrophy in the absence of business models supporting a career creating.
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...
