The Internet can be partially censored, websites can be banned, and governments in dictatorships can even prevent everyone from accessing the Internet. This is because the Internet still relies on centralized servers that ISP providers and governments can control.
But Bitcoin is not, it can’t help it. Bitcoin nodes are decentralized and distributed around the world, it is impossible to shut down. Even if all countries in the world join forces to combat Bitcoin, they will slowly discover that this is simply not possible.
Even in the most extreme case (of course, the odds are very small), all core developers are killed overnight and access is blocked by the International Monetary Fund. Then at this time, users will not easily download the new version, they will only continue to use the old version, because everyone can see what has changed in the code.
There is a big debate now that Bitcoin is largely dependent on the Internet. However, with the interaction of the mesh Internet, decentralized nodes, and open source distributed software, this dependency becomes less important.
There are many mechanisms to solve this problem. For example, you can run Bitcoin nodes using Tor, as recommended by Satoshi.
