Fun Police,
Ever watched engineers putting the blades on a 350? Imagine the loading through the rotor head after the first blade is installed. No problems at all.
If your question is regarding the load through the blade itself, then watch the distance they droop when ground handling across bumpy ground compared to the distance when a carefully placed bum is only a few inches from the mast.
Most aircraft will handle it just fine. Not much to worry about unless someone falls off.
