Actually, Eq. (9) follows from (7), or (12) follows from (11) using HUP. Of course, we cant get the Schrodinger equation without HUP. But the classical Schrodinger equation uses only the length scales. It is when deriving the quantum Schrodinger equation from the classical Schrodinger equation, that HUP is applied. Also, GR does not use HUP. I derived HUP in an earlier paper from Newtonian gravity without using QM. I showed here if the Riemann tensor in GR was zero, position and momentum would commute, thereby yielding no QM.
