I had a really good conversation about this sort of thing with someone who has been to Wasteland, the Max Max-style cosplay festival on the US West Coast. They are reportedly very strict about people always being "in costume" or "in character" (ie: dirty, post-apocalyptic-ish) whenever outside private camp spaces.
I find it pretty ironic that the Deathguild folks from Burning Man are out there, running an event that enforces mandatory culture. Subsuclutre implies depth, nuaunce, context, space to fuck with things.
It's all play, which is what all this ridiculous stuff is supposed to be in the first place. If you want a shallow simulacrum, go to Disneyland.
