Conservation has been confused with the word preservation in too many instances.
Yeah, you're right. The word conservativism isn't wrong, it's just understood wrong.
That reminds me of one thing that really gets me, the left-wing co-opting of environmentalism. Conservationalism is a very conservative action, including in modern politics. As much as they blunder on about it hippies and vegans rarely ever conserved anything natural. Hunting and forestry associations do though.
All the culture we now have collected wasn't part of a collection before. It had real ties to real life in real places for real people. It wasn't an inventory, with a search bar, for buffet like consumption.
Chesterton wrote that all quality organic culture was local peasant culture, and urban folks just appropriated collections of it for themselves. The cosmopolitan considers themselves cultures merely because they consume many cultures, the local peasant actually creates his culture himself.
I think he had a point.
I don't mind the occasional museum, but mass media culture has not been good for organic cultural growth.
