You're assuming that there exists such a cloning process, and in doing so, silently ascribing properties to that process that completely change the outcome. You're in effect saying "Assume there is a cloning process that is instant and creates a complete copy of you, both mentally and physically," and sure, in that theoretical world, you can talk about there being no way to know which was you, the clone or the original. But IRL, we have no way of knowing what the properties of such a cloning process would be - maybe it's impossible to create a cloning process such that mentally, it is a complete copy. Maybe you can always tell whether you're the original or the clone. Similarly, maybe we simply cannot create a digital copy of a mind that cannot immediately tell it is the copy. We have literally no way of knowing. So instead of living in the philosphical realm, we can have a lot more productive conversation in the practical one. Practically, it strongly appears to me that I have continuity every time I wake up, and practically, if you copied my mind and ran it on a computer, that mind would not be the "me" that appears to experience continuity. Practically, it would bring me no comfort to know that this other mind that used to be a copy of my own continues onwards while I die, no more so than it would bring me comfort to know a twin of mine continues onwards.
