A blockchain doesn't make it impossible to censor. To be honest, I wonder why western governments don't ban cryptocurrencies. They make tax collection harder and help criminals collect money. Plus that would be a blow for countries that are investing tons of money in it eg China, which is destroying the rest of the world, economy-wise. There is the possibility that western governments are already under Chinese influence, I guess, but I wasn't definitely expecting BTC to survive so long. Especially because governments are not even benefiting from cryptos.
