They can't "ban" Bitcoin. All they can do is to shut down the on and the off ramps. That's it. As long as people stay in Cryptoland there is nothing authorities can do.
Wait, isn't that Trump's "wall"? Just like the French "Maginot line" to keep out the Germans whenever you build a wall people just go around, over, under, and sometimes straight through it. Yeah for sure someone will figure out the equivalent of quantum tunneling to get through walls. Eventually ICOs will raise enough money to launch their own constellations of satellites to give access to their blockchains (and maybe just host them in space, period.)

Nexus has done exactly that. They're launching satellites to provide internet access, and host a blockchain for their currency.
