"you're 3betting for all the wrong reasons" ---- yes 3 betting to build a pot with what is likely the best hand is wrong? So you dont like to bet your monsters - got it....

"you're supposed to be maximizing your profits vs the villain's entire range" --- I dominate most of his current range so I should be betting to maximize profits. (glad we agree)

"3bet here as your default play with no reads shows a fear of playing post-flop" - Actually I think your the one afraid to bet with what is likely the best hand. The 3 bet is trying to actually build a bigger pot post flop against hands we dominate.

"I just don't think you have enough information" - Again we agree, thats another good reason to bet, to gain information.

-By not betting you don't allow villain to make a mistake.

If you could see his cards how would you play if his range is 10+ A-J+

Against Aces or Kings you would fold; against Q-Q you would call ---- against all other hands you would raise for value. There happen to be way more card combinations of 10-10 J-J A-J A-Q and A-K then pocket aces and Kings.

So most of the time if you could see his cards you would be betting for value.
