That's a money centric worldview.

I don't think advertisers should be allowed to patron the arts, I think they have infected the art space and this is bad for all of us.
I think people would do better, truer art (even if it were of lower objective quality) by not suffering the incentives and directives of advertising.
I see advertising as a corrupting drug for art. While it creates more bulk I think it has made art worse as a whole.
After the "adpocalypse" where were have destroyed every piece of advertising and cleansed it from the stench of marketing.
This post-advertising world would have more art it in, it would mean more it would be better
Nature abhors a vacuum, the death of advertising centric art would create a fertile space for art that is simply unthinkable at this moment.

Advertising and marketing will not gently let go, we have to exterminate it
