If this were true, then more than likely there would be no center line concept or theory. Curving your thrust shortens it and weakens the strike power. It is not always about natural human movement, but more about efficient human movement. Curved strikes are simply not efficient strikes. Even out uppercut, which is sort of an upward hook, comes across on center line.

He didn't say curving your thrust. Your fist may travel in a straight line but the mechanics behind it are curves. Think of the way a piston in an engine works. Your shoulder is a ball and socket joint, it can only move in curves.
BTW, a curved punch does not lose power.

No, you are starting to knit pick here. The construction of one's arm dictates that it fold and bend and such in any action, but the fist can still travel on a direct and straight line. That is what is meant here and you I think know that.
And no again. The curved punch is not really a punch, but more a hook, and you can simply not put the same structure behind it and the accuracy and the structure of the wrist is simply not there. Any straight forward punch with good structure behind it will always be way more powerful than the hook. Not to say a hook will not damage you, as we all know that it will, but it will never carry the same power or wrist structure.

What he is saying, and youre failing to see, is the forearm is driven forward by the rotation of the shoulder joint.
Nonsense. If you think hooks dont have structure/power then id suggest you spend an hour with a boxer.And no again.
