SpaceX would tell you to look at how profitable is Starlink. Two things about that: you have to replace the infrastructure every five years while terrestrial infrastructure electronics lasts at least twice as long, and inert stuff like towers and fiber lasts for decades. And you can drive a truck to where it's located if there is a problem.

Secondly, terrestrial infrastructure keeps expanding into the rural areas that Starlink counts on for most of their TAM. Except for ships at sea and extremely remote places, the Starlink TAM is chronically shrinking.
