Why can’t MJX Hyper Go 16213 aluminum front guard replace a front bumper?

Why can't the wear-resistant aluminum components equipped on the front of MJX Hyper Go 16213 electric overdrive version be used as a bumper?

MJX Hyper Go 16213 aluminum front piece is engineered mainly to shield the chassis front from abrasive ground contact during off-road running, focusing solely on wear protection. Without built-in deformable shock-absorbing structures, it offers zero crash cushioning.

In the event of a heavy head-on collision, impact force transfers straight to the main frame, putting mxj hyper go 16213 internal components at high risk of damage.
