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.
