I'm not sure about this actually. AFAIK, traffic between nodes is not encrypted, therefore it could be blocked by governments through packet inspection.
I think it's a bit too difficult to do this now, at least for the major cryptocurrencies. The US gov would be crashing an entire financial market just so they could have it their way.
Would most of the public care if Bitcoin were banned by the government? Maybe not. But i sure as hell can assure you the people who've invested in the 200 billion mcap certainly do!
If Gov sees choice as disrupt blockchain & piss a bunch of people off & damage economy for awhile, or cease to exist, it will pick the former. It's an existential crisis for them.
