Hi Akinbo,
Though energy is quantified, that does not mean that the Planck constant is a minimum energy, and hence the Planck length the smallest possible length in the universe.
The short reasoning* is that since in blackbody radiation there are more energy levels per unit energy interval at higher energies, temperatures, so we need more and more decimals to distinguish successive energy levels, the energy gap between subsequence levels can become arbitrarily small: though energy is quantified, there is no minimum limit to the size of the quantum, so the Planck length and Planck time etc. have no special significance.
The Planck constant h is like the number 1 in mathematics, encompassing all values between 0.5 and 1.5, so if we can measure the Planck constant in more decimals, at higher energies, then we can write that number as 1.0, which encompasses all numbers between 0.95 and 1.05.
So if in our equations we set h = 1, then every time we improve the accuracy of the Planck constant, then we increase the magnifying power of our microscope with a factor 10.
Though there is no smallest distance, to what extent spacetime itself is detailed depends on the energy density somewhere: the higher, the more detailed the spacetime area is.
*For the long reasoning, see my 2010 FQXI essay http://fqxi.org/community/forum/topic/838
Another point is that if we do live in a self-creating universe where particles and particle properties are as much the cause as the effect of their interactions, then two particles only would be identical if they would be at the exact same point in spacetime, if their environments would be identical.
So instead of saying that interactions between particles become weaker because distance 'dilutes' the property of one particle as observed by the other, we can as well say that the properties of particles become qualitatively more different as they are farther apart, as if from the point of view of a nail, say, a magnet turns more and more into a cork as it is more distant.
This means that your monads not only have no minimum size, they can also differ qualitatively, the difference changing gradually, a difference which is observer dependent.
