I want to completely remove a leaky saddle valve which once

What's the best/easiest way to permanently remove the valve
and seal the remaining hole in the copper pipe? I prefer NOT
to cut the line and solder in a coupling.

the way to seal it is the way you dont want to do it........
wont take long, but will last long time.. cut the copper pipe and clean
up the joint area and the joint... pull the pipe apart and put in the
joint with flux on it. then heat it up and put the solder to one side of
the fitting and then the next.....dont try to patch up the small hole..
the company that built my house repaired a nail hole in the copper pipe
for the kitchen sink... a few years after moving in we could fell the
floor (concrete floor) kinda hot right infront of the sink... traced the
problem behind the sheetrock under the kitchen cabinet.... the tiny nail
hole that was soldered finally leaked....just cut out a piece of copper
tubing and replaced that whole secton of 2 feet....
