Two things are qualitatively different if no amount of either one can serve as a viable substitute for the other; TNT and U-235 are qualitatively different explosives mostly because TNT does not generate neutrons.
The construction project that makes a planet be scaled down to make one person, and the project which makes a galaxy cannot be scaled down to make a planet even though creating galaxies involves creating planets: The process by which a galaxy is created cannot be scaled down to make a single planet.
When I say that two processes are identical, I’m talking about a theoretical or mathematical identity, not a practical identity. If you can reverse information-theoretical death, then, at least in theory, time travel is possible; he same device may not be able to do both, but the one implies the other.
… Okay, so we’re talking past each other. Define “qualitatively different,” please.

Oh, I see. Fair enough.
