We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
What is most art "for"? Well, it's to be decorative or at least interesting. It can be social signalling or status-seeking. It can be used for investing or money-laundering. I suspect all of these things have applied since the Renaissance.
Most art is not the pretentious message-bearing stuff you see. What did DaVinci say that the Mona Lisa's smile meant? How did Michelangelo explain the significance of his statue of David? Pro tip: if the artist needs to tell you what his or her work means, it's not art. At least not great art, and probably not good.
