i'm not sure i agree that bitcoin takes "social" out of money. the whole point is that monetary policy can only be changed with social consensus, that's what makes it decentralized.
i personally agree that tail emissions are a bad idea. i'm also not a fan of drivechains. but if a majority of nodes say that's a valid block, then that's a valid block, full stop. if that's not the definition of monetary policy controlled by social consensus, then i don't know what is.
