Why would putting tape on the olive lubricate the threads?

It doesn't - but it might help create a seal if there is a very fine
scratch on the outside of the olive that is causing a slow leak.

If you are going to use lubricant on the threads Jet-Lube V-2 Plus is a
potable lubricant.

Why would you want lubricant on the threads? I've never managed to strip
them.

Mainly when you want to do up a fitting in a confined space and can only
get short spanners in there. You can then tighten them better with less
friction to fight.

(Jet lube also works - although is a tad more messy!)
