This is not what microservices solve.

There'll always be critical microservices that keep your app running. It doesn't matter if all your other services are running if the one serving up core functionality goes down.

If your engineering rigor is so poor that you can't get reliable failovers with a monolith, god help you keeping microservices running.

Hence “assuming proper vertical separation”. The same applies to monoliths, so not really an argument.
