If we are not empty, we become a block of matter. We cannot breathe, we cannot think. To be empty means to be alive, to breathe in and to breathe out. We cannot be alive if we are not empty. Emptiness is impermanence, it is change. We should not complain about impermanence, because without impermanence, nothing is possible.
