Presume governmenrts agree they want to get rid of Bitcoin, this wouldn't be through a computation attack, but by forcing ISPs to ban the bitcoin protocol.
No.
Reason number 1: Reminder that the tor network exists
Reason number 2: https://www.bip324.com/
Reason number 3: "The internet is a network of networks" If your ISP tries to ban it, just route around them. We can do IP protocol over mail, with Pidgeon carriers, WISP (wireless internet service providers) internet over radio, internet over satellite any method you can think of to communicate, you can do internet with it and therefore, you can do Bitcoin with it.
I like seeing people ask. Makes it clear that yeah, this has been answered. New people are always coming to bitcoin and its good to see how long ago these questions were answered.
ISPs can block a particular website / URL by preventing that route from being resolved through DNS but they can't do much about the encrypted data passing over the wire once a connection is established. It's a constant game of whack-a-mole.
I have wondered if they could block all encrypted traffic unless specifically authenticated by E-ID or something similar, in a future dystopian scenario. I doubt it, since I haven't seen anyone talk about it, but it would be great if someone who knows a lot about networks and the internet could explain why it would be impossible in that case.
The reason I wonder this is the weird and dystopian laws that are being proposed here in the EU, and in the US, UK, etc. The one here in the EU (Chat Control) would require surveillance and age verification (i.e. identification of users) for pretty much any service that can be used for communication. As the internet is today, such a law would be pretty much impossible to enforce.
It’s been answered many times but it’s still good to ask. It’s a logically legimate worry, but just not possible. Short answer is NO. Longer answer is a lot more words but it really is still a hard no.
