No one is considering that the owner may have reinforced the roof from the inside either. Wouldnt be hard to determine where the straps are crossing the peak and add reinforcement to ensure the straps dont deform the roof, further adding to the structural integrity.

I find it so weird how people will spin a narrative based on assumptions and just disregard all the other possibilities.

If they buried concrete blocks, I bet you they had the presence of mind to reinforce the roof.
