I'm not saying that it really is a blegg, but that if modern art is a blegg, and the NEA stuff is all bleggs, then this is a blegg too.

I would be surprised if the aesthetic value

The pro-spending public money on art/pro-art/pro-modern art "side" also argues that aesthetic value isn't as important as you seem to think it is.

Once again, military planning at any level and/or execution of plans is short of aesthetic value to the average person (usually?), and requires various amounts of background to understand, but if all these other things are "really" bleggs despite also having that deficiency, let military spending be considered public spending on art, let a tenth of it be considered spending on art, and the USA spends more on art than any other country.
