You started out by asking how you were supposed to relate in any way to a copy of you . What I’m gathering from our subsequent discussion is that this was a rhetorical question; what you actually meant to express was that you don’t relate in any way to such a copy, and you don’t feel obligated to.
I accept that you don’t, and I agree that you aren’t obligated to.
Identity in the sense we’re discussing is a fact about the mind, not a fact about the world. If you choose to identify solely with your present self and future selves in the same body, and treat everything else that could conceivably exist as not-you, that’s fine. It’s a perfectly reasonable choice, and I’ve no doubt that you can come up with lots of perfectly valid arguments to support making that choice.
The fact that other people make different choices about their identity than you do doesn’t mean that either of you is wrong about what your identity “really” is, or that either of you is ignoring reality in favor of “wishful thinking”.
There are consequences to those choices, of course: if I choose to identify with me-now but not with me-in-ten-years, for example, I will tend to make decisions such that ten years from now I am worse off. If I choose to identify with me-in-this-body but not copies of me, I will tend to make decisions such that copies of me are worse off. (Obviously, this doesn’t actually create consequences in cases where none of my decisions can affect copies of me that exist.) Etc.

Yes, it was rhetorical.
I see now, I was operating on the fact about the world level.
