Did you read the paper? There exists a technology that has purely enforceable property rights. What is that actually worth? I don't know.

Yeah yeah, I've read the arguments about liquidity issues, shutting down the rails, making it illegal to trade, etc. but that's beside the point and depends on a thousand future variables to play out. So I don't know if btc will make it or not, but I do know property rights mean everything to humans. They literally determine whether not one is a slave (I am my own property). So just the ability to have a technology enables pure property rights to a world where nobody really has enforceable property rights over anything seems pretty interesting to me.
