This is literally what happens all the time for all Internet users though wires and fiber on ground-based internet at similar or worse single-hop latencies.
The number of domains is irrelevant since most of those requests would be asynchronous. What matters is the number of hops that the traffic needs to take and the latency for each hop.
1.9ms times any reasonable number of hops would still produce a sub-100ms latency which is the FCC sites as their requirement, and would be a perfectly serviceable latency for nearly all Internet use (and is around what most users experience now).
It is unclear why the FCC would reference "the laws of physics" as a barrier for StarLink achieving this, as it is unclear how they would be causing any problems.

- FlyingAvatar 6y agoIf conventional geosynchronous satellite internet can achieve real world latencies between 600ms and 1200ms, can you describe a scenario where having a hop time that is 60x faster could not manage to improve this by a factor of 12x?
- shaklee3 6y agoThink of it this way: traditional geo satellite has a theoretical latency of 430-500ms in most cases. That means there's AT LEAST another 100ms purely due to processing delay and other hops, but typically much more.
