Well, Starlink has been known to provide roaming services in countries they haven't reached a full agreement with yet, with the exception of the ones who legitimately might have the power to shoot down SpaceX satellites if they got angry enough (India, China, Russia).

The number of Starlink satellites and the rapidity of their replenishment vastly outnumbers the number of ASAT interceptors, and launchers, that any nation could produce.

Shooting-down Starlink satellites is economically infeasible, never mind the fratricide it would cause to the aggressor's own LEO assets.

True, but it would still be a very expensive inconvenience for SpaceX, I think enough that it isn't worth serving roaming users there and pissing off the countries.
