You're right. It's silly, :-)
The difference is that we are bounded on the x,y,and z axes by the laws
of physics, and we move on the t axis (your "w axis") at a fixed rate,
also bound by the laws of physics. There is, however, no obvious law
that bounds how far we can go on the t axis. (more precisely, there
are such laws, but we are not at all close to those limits.)
Alternatively, all the extropians who are space travel evangelists
are working on those axes.
