In neither place, nor any country with mandatory ID as far as I know, you get "no access to anything". The worst thing that can happen is that if the police choose to stop you, not carrying your ID can lead to you being taken to a police station temporarily. Which is not great, but not anywhere near close to what you are suggesting is inevitable. And police can detain you arbitrarily in places without state-mandated IDs, this is just a cute excuse that they can add to their repertoire.
