Extremely obvious they would consider this, to the extent that it's one of the independent arguments against valuing Starlink as if it has a shot at being a global monopoly. Ditto space-based data centres.
Space is hard place to attack in the first place, but even harder to defend against attacks from those who can reach it.

That said, the ongoing improvements to lasers, and price reductions, in a decade I expect the limiting factor for random terrorists performing such an attack would be adaptive optics to get past atmospheric distortion.
Agree in a decade any rando will be able to accomplish this.
Like shooting down all Russian satellites in retaliation? The US can produce and launch new satellites much faster than Russia.
