I think this needlessly focuses on one not terribly typical scenario. The earliest uploads will likely be cryonics patients, without much hope of getting a regular body anytime soon. When uploading tech is mature, making an upload copy of a flesh brain probably *won't* require destroying that flesh brain. And making a copy of an upload brain probably will never require destroying the original (though that may be cheaper sometimes). It's only in the early but not earliest upload tech era regarding meat to metal transitions when the issue might even arise.

I mainly want to point out that not only is there a lot of slop in deciding "is it a change me or a similar someone else", but even when you decide "someone else", you may still be willing to sacrifice a lot to create that someone else. Maybe even "die". When uploading is possible, many people *will* do it. Can't we get past this endless agonizing over who will do it, and wonder what their world will be like?
