Please answer
What is e standing for in reality to make it constant?
And why would you use a constant that has no
representation in reality?

As I understand it, e is the speed that the propellant shoots out of
the back end of the rocket, measured relative to the rocket. What's the
problem with that?

Such (the speed propellant shoots out at) is not a constant.
It has acceleration and also has a top speed and an end speed of
0 after it stops.
So it is wrong simple as that.
and...It is not a constant at all.
