I'm guessing you think good handling = no body roll also?
Good handling is LESS body roll.
If you had a rigid chassis with no body roll whatsoever I don't think it would handle that great to be honest.
I'm no engineer though, so correct me if I'm wrong
I'm not an engineer, but I think I understand body roll well enough:
The main reason you want to reduce body roll is because it interferes with your suspension geometry. So you set up your camber and caster and toe and it's all nice and good sitting on an alignment machine, but when you're moving around, all those values change as the suspension compresses and expands. Excessive body roll contributes to handling issues by changing the geometry of one side of the suspension with respect to the other, which can lead to effects like roll oversteer. It also reduces load on the wheels on the inside radius of your turns by shifting the car's centre of gravity (CG) more toward the outer radius, which in turn reduces your overall grip (though the extra weight on the outer radius will increase their grip somewhat - which is part of what creates roll oversteer). It also has some other less ideal effects, obviously the more you load up your tyres the hotter they'll get and faster they'll wear out.
There is of course extreme body roll, where you are rolling so much that you might find yourself often pulling two wheels off the ground, or rolling the vehicle over, but aside from a stock Volvo with blown shocks I don't think we ever have
that much roll. That's more a 4x4/truck sort of problem (edit: or maybe if you have really wide sticky tyres, but otherwise I think you'll lose grip before you roll the car)
Having no compliance whatsoever would lead to a number of problems, like having one wheel off the ground on uneven surfaces, or not being able to store energy in your springs for powerslide entry tricks like the
Scandinavian flick.
