Curiously, Starlink so far is not licensed for frequency reuse, which makes
me quite curious how an 8x increase in satellites will result in a similar
increase of bandwidth per square km.

Completely agree about 25 Mbps being comfortable when latency is good. We
(at Preseem) have a lot of data on how much bandwidth is used per nominal
speed plan, and while the initial increase is steep (a 10 Mbit user is
often constrained these days), above 25-50 Mbps, the slope is about 2:1 --
that is, a 200 Mbit user causes only about 2x the load of a 50 Mbit user.
