I sure hope governments and crypto industry leaders work together to make our world a better place. A full ban from worldwide countries, would certainly stifle Bitcoin's ability to reach the masses. I'm pretty sure most governments will regulate the industry, instead of going against it. As long as they're able to tax Bitcoin, there should be nothing to worry about.
I think governments will eventually admit that Bitcoin cannot be stopped no matter what. We can thank Satoshi and the rest of the Bitcoin community for keeping it as decentralized and censorship-resistant as possible. If Bitcoin was centralized, it would've been doomed by now. Who knows if it gets to live alongside Fiat for generations? Just my thoughts

I mean of all of the major forms of "currency" in the recent history of man, Bitcoin is the one with the most censorship resistance. Gold was better in this sense than fiat, but still not ideal because the very physical nature of gold made it difficult to transport and trade in, and susceptible to government intervention. Fiat is totally regulated by the government it is issued by, its completely centralized. Bitcoin isn't - but its not anonymous either - that is something a lot of people don't understand. Every transaction publicly available in the blockchain and allows forensic analysis. But at the network level, it is permission-less, there is no human intervention that decides if a transaction is allowed or not.
That is what makes Bitcoin censorship-resistant, and more so compared to other kinds of currency.
