There's no way governments will be able to enforce regulations on truly-decentralized blockchain networks. It's technically impossible.
True, but as we've seen in this thread, bitcoin is not actually censorship resistant. If the government get 51% of mining power to comply with their blacklists, then they can simply censor any transaction paying to or from a non-KYCed address.
How likely is that to happen? Either from the US government or BlackRock.
It's a huge ASIC investment to acquire 51% of the hashpower. Billions of dollars are required, maybe trillions in the future.
Not to mention there's tons of competition:
