Really? I would have thought anti-sieze would be better, as there's no force trying to loosen a freewheel (and in fact a massive force trying to screw it on tighter), the only issue is preventing it from corroding on. Ditto the pedal threads.
[Edit]
And as for BB cups, I think the poster is talking about on the threads, not the bearing surfaces. Only a complete whackjob would put loctite on the bearing surfaces...
[Further Edit]
The grease on the threads in seatpost binders acts as a lubricant. It reduces the amount of tightening force on the bolt to get a given amount of tension in it, by reducing the thread friction. Less friction on the threads means less work to be done against that friction, so less force required to turn the bolt by the amount required to get it to the correct tension.
