Well firstly xyu I think you are over estimating the ammount of times the villain will double barrel this turn with a hand worse that ours. Most 100NL guys are doing this pretty much never so the possibility of us getting bluffed off the best hand is slim.

Secondly you need to consider the type of ranges the villain cound have on a flop like this and out equity against them. For example he could have a paired hand like 99 or a pair of queens. We are pretty much flipping on the flop with these hands so raising and getting them to fold or call is not that great. Or he could have a hand like A8 which we are ahead of. Once again raising would make this hand fold but that would be bad because we were winning against that hand. The other hands in his range are stuff like full houses and strong trips, all the hands that he will never fold if we raise. We're actually a pretty big dog to this portion of his range and if we raised and he called/reraised with these hands that would be very bad for us.

So in conclusion, if we raise the only hands that play with us are ones that beat us badly and the only hands that fold are the ones we beat or flip with, hence raising is a bad play.
