In the West we have reasonably decent government. In other countries, not so much. You are a law-abiding citizen today, and tomorrow you are a criminal whose assets should be seized. Just ask my family that fled communism!
Btc won’t protect you against a government that is willing to show up to your house and send you to Siberia or shoot you in the head. The “sweet spot” of a sufficiently corrupt country where seizing wealth is common but Btc would protect you is pretty small.
