I imagine even if there is a strong philosophical argument that it’s a “you die and it’s a copy/clone that comes out” in this scenario that people would still use it just from social and economic pressures. It would become normalized to work on the other side of the planet and just teleport there, your friends might be scattered across the globe, and not using the tech would put you at a massive disadvantage to everyone.

It’s a fun one to think about though - our consciousness is interrupted at different levels all the time (Sleep, injury, anesthesia etc), would a teeny tiny interruption from being rebuilt, make you any less you? Perhaps the scary thought is “you” aren’t something continuous, and that teleporting (dying/being rebuilt) isn’t really that different than just normal living.

All that said - I’d probably grow up with the technology and use it while trying my best to never ever think about the details!
