Good observation. Per's system seems to be unconcerned with gravity and does remind me of projects done by a colleague, the late Prof. Jim Fitzgibbon, for NASA--weightless sturctures to float in space.
As often pointed out, Per's system is homogenous, with every segment like every other, whereas in gravitational conditions loads accumulate, requiring some portions to be stronger (larger) than others. Efficiency require loads to be carried to the ground by the most direct route possible--which is hardly Per's way of doing it!
Per seems to suppose that so long as the assemblage is rigid and will hold together, it shows promise. That doesn't make it efficient, however, and this sort of unmodulated system would be extravagantly overstructured and inefficient.
