My family is using a directv antena bought in colombia and paying service in colombia, in Venezuela, so I'm pretty sure the market will try to do that as soon as they lunch in colombia
Starlink is an active two-way system. Not only are they using high precision beam guidance on both ends, the receiver also has a GPS antenna and will report it's location back to the network.
Starlink is capable of turning off groundstations that are not where they're supposed to be. Not only capable, but for 'fixed location' groundstations (i.e normal service), they actually do block service if you move too far from where your assigned service area is.
