You clearly haven't been paying attention. Nobody is denying that it's possible to build a model in which the upper 10% is incapable of crushing down the other 90%. What has been pointed out, over and over again, is that results on models do not reproduce either the complexity or the scale of the 9/11 collapses; what has also been pointed out is that Heiwa's "axiom", that it is impossible for 10% of any structure to crush down the remaining 90% in any circumstances whatsoever, is pure and utter fantasy.
We don't oppose Heiwas because he contradicts the groupthink. We oppose him because he misrepresents his fantasies as sound engineering principles, and on that basis accuses innocents of mass murder. He is a liar and a fraud, and no amount of handwaving about lemons or pizza boxes will make him anything else.
