There's other potential advantage (or disadvantage depending on how you view it).
Some countries like India don't like sat phones on their territory.
Some countries like Russia are ok with them but require local connection to terrestial networks and local licenses.
Some countries are in territorial disputes.
What if SpaceX or other such company decide (or would be "gently asked to") it could ignore local regulations in such country? What if it would be done for good?
Possible example: somebody lobbies ITU(via some kind of "emergency license for humanitarian purposes only") to allow SpaceX to allow SpaceX to serve Gaza for free with limits and USA is ok with it. Israel is against it but what they could do? Jam Starlink? What if they also use it? What if 10 years in future same thing is done to North Korea(it could be even more legal - as far as I understood, both Koreas claims they are only legitimate goverment of Korea so SK could issue formal license)?
