I think that’s mostly theoretical. There’s a lot of hardware on long connections that adds latency. The signal also may take fairly large detours (in some cases, it may even hop via a geosynchronous satellite. That adds about 70.000km to a trip, and another 70.000 for the return signal. For most users that is a thing of the past, though)
For example, when I ping microsoft.com, I get something around 100ms (Aside: what does that time mean? Round-trip or one way? I read a few man pages for ping, but couldn’t find out)
There also is the weirdness that, when pinging apple.com or google.com I get about 6 ms. They must be playing tricks with DNS.

It mainly acts as a lower bound. If your pings return 5ns, you know that answer cannot possible be correct. But I agree that's a rather constructed use case.
