I agree and I am not suggesting that at all.
What I am asking is, is there a rule of thumb that says your tripod ball head combo should support "x" times more than your camera and heaviest lens?
I followed the other thread on Ball Heads, and I'm sorry, but I'm just not buying all the hype behind all these really expensive ball heads unless you have a specific need for them.
So with that in mind, I think it might be better to decide what you have, what you dream to move up to, and then pick the ball head leg combination that will suit you now AND in the future. But all this "I have "XYZ" ball head and love it" comments are just fluff, and dont really do anyone justice.
It would be nice to know, what are the base lines in choosing a ball head tripod set up so one does not buy too little and end up having to spend more, or buy too much and end up having spent too much.

I think it has more to do with the mass at the top of the tripod/head in relationship to the area of the base at the bottom of the tripod. There has to come a time when even something that will hold 100 pounds becomes unstable and top heavy under load.
The ball head may be capable of keeping the camera and lens steady, and the legs of the tripod might support that much weight, but the weak link is the area of the base and how much it is able to support such a top heavy set up without toppling over. I think that is often overlooked in these discussions. The great pyramids are built the way they are for a reason
