"Tethers in space, break" for a long number of reasons. NASA has actually tried to use tethers in space several times and found a lot of surprisingly tough issues. One of the least obvious induced current, but read up on it as there is some really interesting engendering involved. So, from the perspective of someone who you want to ride in a tin can at the end of one of these you are really going to need to say, if these break the occupants survive due the ability for each half to reinter the atmosphere, be rescued or whatever.

Now run the numbers for a version of that a reasonable person would actually be willing to live in for a full year and perhaps he would be willing to discuss it. However, a moon base is probably both cheaper and safer.
