That's a valid aesthetic norm to adopt, and I can see how its a practical one if history and culture strike you as too expansive and disorienting and if you feel like you need a strictly conceptualized aesthetic in first place. It sure precludes a lot of art that others have found especially stirring, though, and rejects much of what empowers art to be communicative in a social context. It's valid, but extremely narrow and devaluing, so probably not the norm to expect many artists, patrons, or casual appreciators to adopt for themselves.
