In the case when you die, but your brain still exists, and it starts processing it again in a new host (computer or organic), isn't that not you anymore? Why would my former self want that? Is this a solved philosophical problem for which literature exists?
The you that is now, pre-preservation, will be dead.
The you that is then, post-restoration, will be alive and believe and behave as if they are you.
It's convenient that this process (as described) kills you, because that simplifies things quite a lot. Scanning is more complicated, and I suspect if technology ever arrives that allows for it we will treat such scans as "heirs of the body" -- meaning they will only have such assets as you give them, although of course the IRS will still find a way to get them to pay your taxes.
