You need some way of inducing distributions in reality, ie., making the ice cube. If you're just subject to time-varying, random, stochastic, perceptual distributions you have no way of estimating the properties of the data generating process (reality). You need to be the one in control of the distribution in order to study it: this is the lesson of the whole history of science as an experimental discipline.
