Simple? answer:
Crews should'nt perform, among other things:
CFIT, land gear up, collide with other aircraft, you name it
Still regulatory bodies decided that we should carry GPWS, gear horn, ACAS ... and that they have to be conveniently designed and reliable.
Those are reasonable expectations; but, in the hierarchy of "essential conditions for flying", sufficient airspeed is, surely, top of the list.
