You can't kick Peano's axioms.
What is your point? That things don't exist unless you can kick them?
Real things kick back. Maths kicks back...
Only metaphorically.
The laws of physics prevent you from traveling at a speed more than
~300,000,000 m/s.
A curious choice. The 'laws of physics' say light travels the same speed in vacuo in all
frames. The number 299,792,458 is just an arbitrary conversion factor between meters and
seconds.
The laws of arithmetic prevent you from writing down more than 2 distinct
factors of 17.
17 = (17/4)*4
I've got a million of'em.

They seem equally forceful, each in their own way. The laws of mathematics may be even
more forceful, for it is conceivable in some physical universe you can go faster than
the speed of light in this universe, it is much harder to conceive of a universe where
you could write down a third factor of 17.
