One of the first state machine you'll ever learn about in undergrad permits transitions from a state back to itself, so I don't see this as a barrier.

  And you can implement /dev/null with multiple states, as long as you make them all behave the same way.

  The claim is not "it's a state machine" but about transitioning from one valid state "to another". That requires more than one state.
