"My biggest concern with the big bar argument is the chassis. If the suspension can't move, the body will. Also, impacts will be transmitted to the occupants of the car."

My biggest concern with the above "arguments" is they may be taken literally. IE, no "bar" stops the suspension from moving, EVERY chassis flexes, ALL "impacts" are transmitted to the occupants in a non active suspension car. And "everything effects everything else". Its a matter of degree and personal preference that we decide on.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
