Sure, but even if these planes managed to somehow cost as much as a starlink satellite, it'd still be cheaper to do it this way because having some dude toss it up into the air for takeoff is basically free compared to even a fully reusable Starship flight.

Plus it can be deployed on an as-needed basis. Large concert in a rural area? Hurricane destroy your city's infrastructure? Toss up a few planes and get the service you need for a week or month until the situation is resolves. (At least that's the theory... I hope this technology works as planned.)
