This interpretation of renormalization supposes that there is a more fundamental theory at a higher energy scale from which the quantum field theories arise. These then have an effective field theory which is evolved to the energies that are used in current experiments. During this evolving the non-renormalizable interactions go down but not the renormalizable ones which suggests an explanation why we only seem to need the renormalizable ones. However, if one starts out with the idea that something more fundamental exists at higher energy scales one has already proven that QED is 'wrong' in the sense that it is not a fundamental theory.
