Though the simpler solution is that perhaps memory formation is paused over the period then the person ‘lost’ their memory to sleep.

Losing memories when you’re wide awake is like a file system deleting pointers to a file. The file is still there, just inaccessible.

Anyways I feel that the assertion that “Creating and destroying perfectly identical copies of the information that corresponds to a person neither creates nor destroys people” is extremely dangerous thinking that could lead to the premature end of consciousness for some very unfortunate individuals. After all, they’re perfectly identical and we have no documented instance of anyone sharing consciousness, so it may be that consciousness are unique and not commutative.
