Why not consider the case where you only have the tips of the pole. Take
two masses on the ends of a light rope, and swing them around your head.
Make it even simpler, and just consider one of the masses. What stops you
from swinging it around your head (on a very long, unbreakable, massless
string) until it's moving FTL?

Exactly the same thing that stops you from moving it at FTL in a stright
line - you need to have infinite kinetic energy.

You do not need infinite anything to get a finite answer of a speed.
If the answer of what speed it is doing is "186,000 mile per second".
No inifinities are needed for such a non infinite speed.

What's the kinetic energy of a rod of 1 kg whose tip is moving at
186.000 miles/second, James?


The only thing stopping it is the problems with what happens
to matter at that speed.
Nothing infinite about any of it.
