Okay; poor people, who can't afford to buy very many, or any, full-price new books, don't matter. I must have missed the memo on that one. About poor people not mattering.

Library patrons don't matter, since the libraries steall all of their books. Presumably. For this argument to work.

People who visit art galleries to look at, talk about, write about, and presumably popularize, say, paintings, don't matter, or at least not unless they buy original works by recognized artists.

There is no genuine participation in culture except through the market, by individual end-users who pay full price.

Well said, OP!
