Implications of Teleportation Technology

Oftentimes, in discussions about teleportation technology, a fact is neglected, namely that it implies making a copy of a person (and potentially destroying the original).

For society, it would have numerous implications. For instance, people could purchase a personal teleportation device (for their home, for example), and then modify it perhaps to make copies of themselves instead of destroying the original. People could then proceed to make an arbitrary number of copies of themselves. Hookers for instance could send copies to clients. Companies could send copies of employees. And so forth, the possibilities are endless.

It would then make sense if there were personal destruction devices, which could be used by copies (or originals) to destroy themselves after use (voluntarily if convinced that would be good).

Interesting are numerous implications there: How does one distinguish a copy from an original, if they're a 1:1 copy? How does one control black markets of teleporter copies? For instance, a person could sell copies of themselves. Also, since the people would be identical, they could share their public identity (social security number, bank account, passport, etc.)

In deep space travel and colonization, such devices would be essential to populate spacecraft and planets, because deep space travel might remain infeasible for a long time to come, while data transfer over vast distances might be possible.

In space, since overpopulation will never be an issue (due to almost infinite space), a person could have an arbitrary number of copies of themselves. All people and copies combined could probably not fill the entire universe even if they keep on making copies of themselves for a very long time. (Also, older copies would probably die in time to prevent the filling of the entire universe.)
