There's always a leak in the system because of this, even if you brought down the hammer on every exchange. Destroy Bitcoin and it'll just mushroom up again in some other form.
Crypto is game-theoretically useful even to elites who suspect they're under threat of being frozen out; they might not be able to keep 100% of what they have, but even 0.1% of vast riches is enough to sustain a comfortable life for some time. And if they lobby to keep exchanges open, they have the possibility of keeping more. This explains why there hasn't been a strong global consensus on crypto yet.
