Quantum Gravity only becomes a problem when we probe below the Planck scale. This is because we don't know what occurs inside a singularity in a Black Hole or in the initial condition of the Big Bang when the universe was supposed to be in Planck density. The Planck scale is also the origin of the trouble of what to make of a metric that is in quantum fluctuations.
So how come we don't just assume that minimum resolution of nature is the Planck scale. Meaning there is nothing below the Planck scale because the Planck scale is the minimum pixel of nature. Then there is no need to search for quantum gravity and no trouble about metric in quantum fluctuations.
But how come this is not simply assumed and the solution? What problems or other conflicts would come up if we simply assume this?
