My perspective: go with what the person who created it agreed to. They’ve set their life up around certain assumptions, and if I don’t like them I will forgo their work.
For example, that person whose works are in the gallery has built their business on a balance of exposure - letting anyone who walks in look at things - and the fact that people who buy art are willing to pay a fair amount to own a physical object for display. Looking without buying is expressly part of their business model.
Book publishing is different, with the author assuming they’ll get payments from readers - much smaller than that artists but many of them. Since I don’t have any ownership rights over their work, I don’t attempt to change the terms.
