Cannot deny there was molten steel!

14. NIST didn't do any video of the tower collapses

You may be thinking of a NOVA program that had an animation of floors "pancaking." However, the debris pile showed that the primary failure mode was floors ripped from the columns, as should be expected, and there were indeed core columns still standing, briefly, after each collapse -- the so-called "spires." They didn't stand for long because the cores were not designed to be free-standing structures; they needed the floor structures for lateral stability.

You are really straining much too hard to find reasons to believe in the sick joke of controlled demolitions with magic silent explosives. Seriously, have you ever asked yourself why you have such a strong desire to believe such abject bullshit? I don't expect you to answer here, but you really ought to spend a minute or two pondering the question.
