The V/I ratio causes rho which causes the voltage???

Nope. Rho is not dependent upon V/I ratios other than those at real
physical impedance discontinuities. I think you know that. V/I ratios
can vary with position along the line and are not constrained to
equalling Z0 or Zl.

I'm curious why you would ask.
