Brake rotors are cast iron. Not something you would want to weld and then use.
They would likely crack and shatter. The cranks are forged steel. Very
different and still potentially problamatic if you weld them due to stresses
imparted into the crank. Having rotors made is not that big of a deal. As long
as there is demand there will be a supply. Even one off rotors can be made
pretty reasonably.

Maybe because new rotors are fifty bucks or less on most cars.

This just occurred to me - and I'm surprised that I haven't run across it
before: Are brake discs repairable by surface buildup weld repair and
regrinding? I can foresee potential problems with this - warping especially -
but maybe this is not an insurmountable obstacle?
I have seen some pretty beat-up crankshafts welded and reground, but this
thread
on brake rotors made me realize that I have never heard of this being done to
brake discs.

Verified. My brand new DBA rotors measure .43-inch thick
