We can establish a way to contract through the blockchain. Then we figure out a way to settle accounts. Probably this would be a commodity. Unlatch from the dollar. Literally everything can be transacted outside of the reaches of the ugly squid-tentacle. The only thing we cannot do is buy territory/real estate. But although they will park aircraft carriers and threaten with nukes, they really cannot stop us from doing this. This will take a huge chunk out of their pie. On that we build, and after a while, perhaps it might take a century, we will start conquering territory back.
