Whether the block (or the part where the block falls onto) integrates during the fall does not really matter as long as the mass goes in the same directory, here we have to assume
- it all stays above the footprint
We don't need it all to stay above the footprint, just enough to overcome the next floor. What that amount would be is unclear, but it is certainly less than "all", based on the observed collapse.
- the terminal velocity is never reached (i.e the dust goes as fast as the solid mass and gets no resistance from air and itself)
I'm not sure what you mean here - some dust will be left behind, and there may be a spread in the velocites of the overall mass of the falling parts, but again, so long as the mass that impacts is enough, the lower floors will break.
- the energy to break each storey is much lower than the kinetic energy of the bulk above, at that moment
And this is pretty much it. No CTist has ever shown any calculations as to how much energy it would take to actually break each storey. They've made some wild claims based on the complete disintegration of the floors, which simply did not happen. Everything else they show consists merely of handwaving about conservaton of energy, with no serious attempts at truly accounting for all the available energy.
