If your consciousness exists right down to conversationally-induced existential dread, what do you care what or where the substrate it exists on is?

Come on'n get your jamaharon on! There are no real rules—just don't break the weather control network.
The idea is that it does not exist. I have this worry about transporters (or would if they were real). I can only look at it as that one consciousness ends, truly dies. On the other end out pops a consciousness that thinks it is the same person, but is actually a new person, who will live only until it enters the next transporter.
In other words, whatever you think the rest of your life is going to be, post-transporter, will be unknown to you, because you will be dead, and that future will be lived by someone who believes themselves to be you, but is not.
I don't say this to be argumentative - I WISH I didn't view transporters this way - it ruins Trek for me if I let myself think about it, and I'd love to be convinced I'm wrong.
Read the "The Punch Escrow". Not star trek but well worth it if you're into this sort of thought experiment.
Always reminds me of one of my favorite books (part of a series) The Collapsium by Will McCarthy. A big part of the book is their version of teleporting which does involve destruction and recreation, but while you're at it you could make more than one copy at the destination...
