The question is a false analogy because clones aren't the same as the original due to differences in their respective environments.
So you're saying that there is no way that you could have been cloned and switched at any point in your sleep or by being unknowingly drug induced?
Im not saying you were or that its even a vaguely probable situation to any extent, but there are infact a number of hypothetical ways where you could have been copied and replaced with another version , neither being aware of it (and its not as if the teleporters can't be immediately next to each other such as an 'entrance-exit' system or where you incidentally come back out of the one you came in) so the argument still stands..
'Lets assume you are open to a vague possibility that you are a copy of an original that no longer exists, how would you determine that? or could you even do it?'
If the answer is along the lines of 'I can't' or 'Even if I was a clone, its obviously still '
me' in hindsight', then it stands to reason that the issue in question is somewhat unnecessary.
