I hesitate to admit photons into the macro realm, considering they are elementary particles and essentially massless. Given the de Broglie hypothesis, I must of course admit macroscopic objects do have wavelengths, and thus macroscopic uncertainty (your statelessness) is a nonzero vlue. For all intents and purposes though, the denominator of the equation causes the wavelength to go very close to 0, as the mass value dwarfs the Planck constant and velocity is always non-zero due to brownian motion. Wave function collapse is interesting and I must admit when it is not induced by momentum, I don't understand it very well.
