> Your country of citizenship should never have the right to revoke your own citizenship.

Revoking a passport isn't revoking citizenship (governments, right or wrong, can do both, but they are separate and distinct acts.)

> But being able to stop your travel once you're outside the country?

Revoking your passport is basically your country no longer vouching for you. Other countries choose whether or not this should impact your ability to travel.
