It was the simple scalar addition of two traveling waves
that caused it to happen.

'Addition' is not a cause. What is the actual cause - i.e. what
exactly causes coax to melt at half wavelength intervals?

Since standing waves contain no
real power, they cannot directly supply any real power.

To be consistent with the definitions EM waves don't actually
'contain' power, but it is certainly true that interference patterns
don't propagate and transfer energy.
