But as the FSO link is point to point, you would need something like a high-altitude platform station (HAPS) like a blimp, UAVs with RF or a RF tower on the ground to receive the FSO signal, and then broadcast it to many users.

Low earth orbit is 3,000 km or so, meaning that's only 10 ms each way.
Odds are good that if you had a mesh network of low earth orbit satellites (like Starlink) you could actually get an antipodal point-to-point video call with less latency than with terrestrial fiber. That's not a function of bad terrestrial switching/routing: it's the fact that light travels faster through vacuum.
