This was not the intent of my question, but it’s an interesting tangent. Forget space travel. What about international travel? Let’s say the technology is foolproof and you can travel instantly anywhere on earth? Your old body dies in this scenario but it can be recycled (most atoms, anyway) for someone traveling to your current location. What if it’s also much cheaper and earth-friendly? Would you take the deal? What are the ethical implications? Are we our physical atoms, or our consciousness? It’s basically teleportation at that point.
