Here's one way to look at it: with conditional branching, one can always write a program to _emulate_ a machine with self-modifying code (if that's what floats your boat, computing-wise) - because that's exactly what older, simple microcoded machines (which don't, of course, have self-modifying code - their programs are in ROM) do.
