I disagree. Driving a small dish antenna only requires a couple of small electric motors. The receivers would be more expensive, and require more power, but they would still be affordable enough.

They would break more often. This was a key limitation of LEO systems prior to Starlink.

but what about the interruption when the satellite crosses over the horizon? you would then need a 2nd antenna that was ready to take over, or tolerate several seconds of lost signal.
