I'm not going to educate you, just google it. It's not some new physics.
Starlink aren't microsats.
There's never been a large laser-linked shell.
Everything you say is kind of wrong.
I googled it extensively way before this conversation and have researched it for a while. There's no economic sense to the size of the cooling arrays needed and the shielding involved and that's simple matter of how black-body radiation works.
