I have found that it is rare in the real world that impeadances are
not complex. Outside transimission lines, there is little that is not
complex.


You just said that resistors have complex impedance and transmission
lines are flat.


Then again when you conjugate match, the imaginary part of
the complex impedances is nulified and you are then left with the real
part.


Reactances don't just disappear. They create a current between the
source and load that must be assessed to see if it is going to cause
any problems. Sometimes it doesn't and sometimes it does.
