Maybe not technically but if the US or EU would ban any business activities related to crypto currencies, the entire ecosystem would collapse. Even if they continue to exist for black market purposes, their real-world usefulness would decline substantially.

You won't be able to track people who have and use crypto if the people who use it do it correctly.

I'll agree with you there, but I do not believe most governments will legislate a full ban.
