Yes, I buy things with bitcoin, and no, you can't find it on the blockchain.
(Or do I? :))

Similarly, maybe you haven’t hit a transaction yet which a government made an effort to block but … are you certain that nobody will ever try to do so or be interested in your past history? If you’re trying to obscure your identity, consider how that would look under existing money laundering if any party led to your real identity being associated with those transactions. If you aren’t confident that no government with jurisdiction will ever care, that’s a factor to weigh on every transaction since you’re leaving an immutable public record.
They wouldn't be able to unless they had over 51% of the mining power, and it would be easily noticed.
Since the blockchain is public all of that can be retroactive, too, so any transaction has the risk that the other party will leak your identity, which similarly disincentivizes other people from taking them.
By that logic anyone in the world can "block" whatever they want by threatening consequences.
