I think you might have the same misconception about the planck length that I had:

"The Planck length does not have any precise physical significance, and it is a common misconception that it is the inherent “pixel size” or smallest possible length of the universe.[1] If a length smaller than this is used in any measurement, then it has a chance of being wrong due to quantum uncertainty.[2]"

I think that sentence as written is itself based on a misconception. The idea is not that the Planck length is physically meaningful, but rather that that quantum uncertainty is caused by the structure of the universe (discrete spacetime). In other words, that uncertainty is analogous to aliasing in a signal.
