Government regulation of crypto exchanges is inevitable, and in the short term, arguably helpful. But the development of decentralised exchanges and a P2P crypto 'black zone' where people can choose to have value interactions completely outside the purview of any governing authority is a crucial aspect of the technology, because it serves as a hedge against authority by saying, 'we are developing the tools to withdraw, the power to entirely block you out of our interaction'. That gives people political capital.
