Me too, but at slower data rates. At 550km above, that’s still a big signal loss by inverse square law. Problem with slow data rates is that they clog up the channels.
Phased arrays work without having to repoint, but they don't overcome lack of incidence (insolation?)
(e.g. we can't build a solar panel that works perpendicular to the sun (or nearly perpendicular) using phased array technology because there just isn't much solar radiation hitting the "dish" in the first place)
I could see it kinda working, at low frequencies. They are not that far away and there's not many things blocking the signal besides your roof.
