I would add that there is a restriction on getting from one "event" to
another; something which might well "possibly matter to an individual".
A space traveler leaving earth might well be interested in what earth
events he can return to, for example.
... The fact that
no observer can *measure* a material object to be traveling faster than
the speed of light is a statement about *measurements* of space and time,
not about "how fast something can move."
John, IMHO this is more confusing, than enlightening terminology. Is not
"how fast something moves" a measurable, involving measurements of space
andtime intervals and the creation of the concept of velocity? Your
wording seems to imply that "how fast something moves" is something in
itself, distinct from, independent of, and existing quite apart from any
space-time measurements.

The distance and time of travel as measured aboard a space ship are
contracted as compared to earth measurements, and the pilot can, by his
clocks, get anyWHERE in an arbitrarily small time, but he will not make
lunch served on a distant star if that EVENT is "space-like" separated
from his present existence.
