It's not.
Tool time, check your 'facts' about the control laws, too.
I assume you mean 'mechanical back-up', not 'basic law'. And in fact in this mode the sidestick will not work AT ALL. Stick back - aeroplane does NOT go up...
The only input the computer has to the control response in normal law (when hand-flying) is to prevent overspeed (a gradual pitch-up at VMAX+18kt, so you are being a bit naughty anyway), and retracting spoilers and/or applying TOGA if you try to stall it.
Other laws just offer various stages of reduced protection and in fact in direct law the stick commends surface deflection, just like a real aeroplane. Ahhhh.
That is a bad thing if you particularly WANT to stall the aeroplane, I agree...
The chap with the aeroplane in the trees crasjed because he left it too late before appying TOGA. The engines were at about 89% when he crashed, but were on the way up from idle and he was v. slow and heavy to start with...
