Huh? Starlink is in the US and his right to operate physical satellites is under US jurisdiction. So even acknowledging this middle-school observation of yours that governments can in fact confiscate property, the only leverage foreign governments have over Starlink is the right to deny him permission to transmit into their territory. (Even then, only because the US mostly respects international agreements on this. The US lets Elon transmit into some countries like Iran without their permission and there’s not much they can do about it).
