I've thought for a long time that if teleportation should ever happen, a best first use would be to send water from flooding in the Southeast to fires in the Pacific coast states. Water is homogeneous enough that you wouldn't have to worry about keeping structure (except at the molecular level) intact.
Actually, if teleportation ever became a reality, you wouldn't have to send water, you'd use it to create water. Essentially a teleportation device would be encoding an object, deconstructing it, then reconstructing in another location.
You could actually remove the deconstruction step and given a suitable raw-supply of the necessary elements, reproduce what's needed.
Essential a teleportation device is a machine that copies. Ergo, you only need to make one, or many two, then it can copy itself indefinitely. No need to manufacturing anything any more. Gold, platinum, diamonds, physical currency all become worthless immediately.
Hunger, need, poverty would al cease to exist.
If it were the case that living things could be teleported - although look at all the problems Jeff Goldblum had with that! - then you could also copy that entity, assuming, of course, that the conscious isn't something intangible, but rather just a function, probably quantum-driven of the thing's brain.
Then you could also imagine that in deconstructing a human being, you could make some tweaks, on a basic DNA level. You could improve people, remove defects, disease, edit stuff.
Back to the fire, you could use it to remove the burning items and dump them, say on Mars - in Elon's fireplace, you could even phase this over time, no need to do it all in one go, the "fire" can be stored indefinitely, I guess until needed.
And then extrapolating this, a copy of everyone can be stored too when you die, recreate your younger body, but swap it for your older brain. Humans become immortal.
Something I've given thought to for some time, it's quite a conundrum.
