I don't think that's completely true. For instance, one of France richest man, François Pinault actually owns a very large collection and hosted a large exhibition in Paris at the Bourse de Commerce. It's not only him, Bernard Arnault, actually the richest man in the world also made a lot of things for art, craftmanship etc... Of course, like you said it's mainly investment and "art-washing". I don't know how much this thing is going for more modest patrons, but I guess they act on their own levels, locally.
Thank you for that thorough insight at Scandinavian mythology and old Norse etymology, very interesting and I'd be glad to read more or this kind of article.
I wouldn't think of Blut aus Nord when speaking about sleep music but here we are. Love that band.
