Free space laser communications are possible, but even then you are only talking about 10s of GB/s, and you cant add more lasers or receivers on a satellite already in orbit.
Doesn’t help, your laser (or RF comms if you are using them) can still only send out a fixed amount of data per second, it doesnt matter if it is being sent to the ground or another satellite, once it is launched there is a hard cap on how much data can flow into/out of it in a given time and there is no way to improve that.

But if you have a constellation of thousands of LEO communications satellites to leverage…
