It may seem unsettling, but there is actually nothing that can stop it, short of 'turning off the internet', which is of course impossible, since the internet itself was designed to reconfigure itself in the face of any disruption.
Bitcoin will prevail, its code does not permit any other outcome.
While it may seem poetic and pretty awesome all around, saying that the internet can reconfigure itself in the face of disruption is a bit of an overstatement, states can and have many times blocked full access to the internet, though small amounts of information have always gotten through in other ways.
I would argue that the biggest threat to Bitcoin adoption is by far the power of the state.
It could work in N. Korea and maybe even China, but such actions may well encounter a bit of resistance in the free world.
