So you would submit yourself to being killed, and allow a replica of yourself which contains the exact memories and brain structure to be created to replace yourself?
How can you prove my perception was destroyed and not reincarnated to the replica?
How can we deduce which latter event is more probable?
Consider the following two scenarios:
1. You step into the transporter room and your body is scanned at the molecular level and you are recreated somewhere else. Only problem is, the machine failed to actually destroy your body at this location. A service technician approaches you and says: "Sir, a minor glitch occurred. If you could come this way we'll manually finish the process..."
2. You step into the transporter room and your body is scanned at the molecular level and you are recreated not once, but three different times in three different locations. Clearly, you, the person who stepped into the transporter room, can't be all three of the newly created individuals. Granted, from their perspective, each of the three are you and fully believes in the success of the transportation process, but logically, at the very most, you are only one of them, and the other two are not. It makes further sense that you are in fact none of them, and are in fact, dead, forever, and not experiencing the world at all.

And what, exactly? What is your point?
