Since I don't plan on hanging off the side of the tower to operate my
station, isn't it more prudent to tune the entire "system", flaws,
feedline and all if my main concern is what SWR my equipment, in my
shack, sees?

No it isn't.  If you're using 50 ohm coax and an antenna that is not 50
ohms resistive, you'll set up standing waves in the coax which will
result in signal loss.  Having a tuner at the rig will protect the rig
from the effects of the standing waves, but the line loss will still be
there.

Far better is to have the tuner at the actual antenna feed point (or to
adjust the antenna to be 50 ohm resistive).  Then you'll have a happy
rig AND minimal loss in the coax.
