I suspect nradov argues that this type of geofencing + allow-listing is not typically what people mean when they talk about "export control", which I agree with.

And while geofencing + allow-listing for sure provide value in e.g the Ukrainian conflict, it's a weak protection compared to goods that are actually under strict export control (e.g ITAR), and will always have to be done after the fact. Russia could for example put Starlink on drones launched from the Baltic Ocean targeting Poland or whatever.
