Hossenfelder's beautiful idea resolves QG/QFT tension

What exactly are the consequences of [STRIKE]h[/STRIKE] going to zero at high energies?

If at high energies h --> 0 it would also mean that the big bang would consist of a near classical bose gas of spin-0 particles without Pauli exclusion.

This suggests another argument against the hossi's proposal. If at high energies quantum fluctuations vanish, then the early inflationary phase of the Universe expansion cannot explain the primordial density fluctuations, which are needed to explain the observed inhomogenities in the spectrum of cosmic microwave background.

But what would happen with the fermi statistics kicking in? Could we calculate the pressure of a developing fermi gas, maybe mimicking inflation?

Fermi-Dirac statistics in the limit h->0 is still a Fermi-Dirac statistics. This limit does not turn the anti-commutator into a commutator.
