John, IMHO this is more confusing, than enlightening terminology.  Is not
"how fast something moves" a measurable, involving measurements of space
and time 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.

Of course these measurements are frame dependent - I gather that is the
point of your above statement.

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.

Your observations are enlightening if clarified, dangerous if left as a
multi-interpretable tease.
