Nah, quantum fields all rest on another dimensional layer. The quantum foam experiences a weak cohesion force that doesnt drop off with distance. This results in clustering of the foam, resulting in clustering of the deeper field. This is emergent on the macroscopic scale as the folding of space time, which is really just the tendancy of energy to condense on the quantum scale.

Or maybe partical interactions being dependant on locality results in a sort of local energy spike as the two particles get closer. This results in time dilation between the two particles, altering the expected rate at which their interactions would occur, effectively setting a hard limit on how close two particles can get without fusing. This time dilation could also be responsible for the emergent property of gravity. Kinda like how doubling the passage of time effectively doubles the measured heat in a volume, given that heat is a measure of particle interactions per second. Twice the seconds, twice the interactions. If time gets fucky when two particals get close enough to interact, that could result in an illusionary force that emerges macroscopically as gravity.

This is all me fucking around but i think theres maybe a nugget of legit speculation in there

We actually don’t know if distance is quantised- while distances smaller than the Planck length don’t make any sense with our current understanding of physics, that doesn’t necessarily mean that it’s the quantum of distance.
