It "stops holding itself up." If you unload the rotor, any air
disturbance can cause so much blade flapping movement that the blade
hits the stops. It could break and come off then. Without stops, the
blade would probably hit a part of the helicopter itself or touch the
ground when standing on the field
You are talking complete crap. If you don't understand the dynamics, please
do not post answers. Hint: watch a r/c helicopter flying upside down.
Unloading the rotor, in isolation to any other factor, is not a problem at
all, even with a teetering head.
It looks like you are thinking of the classic mast-bumping miscalculation
which is brought about by the pilot of a teeter-head trying to correct a
roll, not by the rotor being unloaded. (although the latter of course was a
factor bringing about the need for correction).
Also, unless you are hovering over something really silly, the air
disturbances causing your flapping are subjecting forces equally on both
blades.
I'm not even going to comment on bringing stops into the equation.
