The Internet is controlled by ISPs which are subject to government demands.
We can simply use an encrypted internet connection to connect the node. Use something like dnscrypt for example, and you can connect again with other nodes. I'm not really sure the government wants to ban Bitcoin (blocking their connection) because it's just a waste of resource. They might try to shut down any cryptocurrency exchange though so that people won't be able to cash out. But we can still trade offline, or use something like Bisq.
I don't think government crackdown will happen, but if it does, I believe we can find a solution for that.
I agree. If governments has advancements the crypto community will also having such advancements and it could be more than that. Governments can only regulate local exchnages not Bitcoin itself they might implement a total ban on it but still we are able to use it with secrecy as every problem there will always be a solution. Not all governments are against Bitcoin so I think it is to hard for them to shut down Bitcoin.
