Remember your equation:
Zin = Z0^2/ZL
If Z0 = ZL = 50 Ohms then Zin = 50 Ohms.
Thus you can make the cable any length you want without harming the impedance match.

I'm not disagreeing Alex, and that is good theory in an ideal situation.
In the real world, all things are not equal and less than perfect.
It is so easy to calculate and use a length of coax in a multiple of half wavelength, why not just do it?
