"ℏ measures the magnitude of the violation of the notion of counterfactual definiteness in our Universe" and "ℏ measures the "Unthinginess" of our Universe!" are absolutely spot on.

Please see my article on the meaning of Planck’s constant, where I show how it represents both the minimum degree of granularity that any physical phenomenon can have for any observer, and the constraint that ensures that all spacetime relationships and exchanges of energy or information that they can perceive are consistent, automatically obeying the conservation laws that govern all other physical laws describing the behavior of phenomena as they interact within and with spacetime.

I would really like to know what you think about it.
