I need to remove an old pipe and need ideas as to how to remove it.

The 50-year-old 2-inch diameter threaded galvanized pipe that
horizontally protrudes about a half inch from the cabinet under the
kitchen sink is leaking where it meets the 10-year-old plastic pipes that
drain the kitchen sinks and garbage disposal unit.

The threads are all screwed up so I want to replace the nipple.

I can only see the last 1/2 inch of that threaded nipple but it appears
to go through the 3/4" thick kitchen cabinet into the wall about two
inches (or so) and into a T fitting where the vertical up pipe goes to a
vent on the roof while the vertical down pipe goes to the crawlspace
drain pipes.

The problem is how best to remove the four-inch long (I assume) nipple
when only 1/2" of it sticks out of the cabinet attached to the wall.

One option, of course, is to rip out the cabinet, but, that's a LOT of
work to replace a two-dollar four-inch-ling two-inch-wide nipple!

Is there an easier way to get the 50-year-old nipple out?

Rock and a hard place. The normal techniques for breaking a big
nipple lose won't work too well when they're that far in the wall.
You don't have to remove the whole cabinet, you could cut an access
panel out of the back of the cabinet, open up the wall then remove the
nipple, and patch up the hole. Cut out the back of the cabinet neatly
and you can re-use the piece to patch it. It's in the back of the
cabinet under a sink so the aesthetics are not a big deal.
