And we are going to put that in the hands of Elon musk? Are you fucking kidding me?
Is there a viable alternative? SpaceX is the only launch provider and satellite operator that is progressing at a rapid pace and driving costs down.
Always a good answer. ;-)

The issue with terrestrial wireless links is that you just aren't going to cover every inch of Earth's surface with terrestrial wireless links. At the same time: coverage comes cheap to Starlink. Which makes it perfect for serving areas no one wants to serve. Such as rural areas, anything outside the largest cities in underdeveloped countries, the open ocean, and so it goes.
Places only Starllink can reach are an insufficient and shrinking TAM. The only places a terrestrial wireless provider doesn't want to serve are places that can't afford FWA even though it costs less.
I'm curious if you could destroy a SpaceX Satelite with a basic laser pointers. Easily enough for normal state actors and some university or engineering lab. You need only to track it and shoot your laser up there (its only 500km) and if it can't dissipate the energy fast enough, it would overheat.

Try destroying a can of soda with a laser pointer first…
Oh come on you guys I thought this would be my ticket to 6000 ;—;
To me, the main issue is not the signal itself, but the direction: >The use of those frequencies to "downlink" data runs counter to standards set by the International Telecommunication Union, a United Nations agency So, just another instance of the current admin violating an international treaty the US is part of.
This reeks of SAR (Synthetic Aperture Radar), and we know Starshield sats carry custom sensor payloads that normal Starlinks don't have.

If a giant chunk of the constellation can act as a truly huge antenna, what can you get from that? Super high resolution? Seek/dwell time on a target that is effectively infinite?

Does your laser pointer has a hard upper Watt limit? Consumer grade / privat buyable laser can easily be bought. And would i destroy a soda can by overheating it slowly and steadily because the can has no easy way of dissipating heat and has electronics in it which are not heat resistent?
Solar irradiance in LEO is about 1350 W/m^2 when unobstructed. A space-grade solar panel reflects 5%-10% of that back as light, with the rest absorbed as either heat or electricity.
This should give you an idea of what kind of thermal flux the satellite is designed to be dealing with.

There have been 11 test launches of starship. You might've missed the last one because it didn't do anything new, except shedding parts and exploding less. There's a pretty good chance that program will never beat the cost of Falcon Heavy, or that the technology, like multiple refueling flights to get beyond low Earth orbit, is ever made workable.

...just depends if it's economically viable
