You bring up and interesting point about what could happen if a tie rod end begins to seize. I've never had that problem -- but it seems like that would only be a factor after severe failure. BTW: on the install, the joint doesn't slip at all when being torqued.
In the case of a loose joint, you might try tightening the nut first to draw the joint together, then loosen it. (Again, never had that problem, but it might work)
All said, I think I'll continue to use anti-seize -- it's never given me a lick of trouble, and its saved me lots of time and effort.
