Agree re 1, but point 2 still stands.
They can take more stress than standing, but the scaling law is still there.
If you scale linearly height/section the max stress won't scale linearly because the weight will scale cubically.

But, their bones could also have larger cross-section and a giant could be stockier yet still appear "human like".
