Starship has a payload 10x-15x larger than the smaller Ariane 6 variant.

It seems like for the cost to be lower you would be wanting to fit as much as possible thus impacting how often it is being launched. So not sure if the two have the same requirements.

I suspect that you don't really need to fill all the seats of a reusable 737 before it's cheaper to fly than a single-use Cessna.

Starlink alone will fill Starship’s most-ambitious deployment schedules for years. That gives plenty of piggyback capacity to swamp the market with.
