Because I want a space elevator, tanjit.
Mind you, this IEEE Spectrum article (via Glenn) on the subject is pretty interesting, and tries to address my major worry on the subject (what happens if the cable breaks?): particularly of note is the info on carbon nanotubes (Tim Worstall provides a link to a breakthrough in the mass production of same). We're all used to blue-sky statements on space; this may be more of the same, but this stuff looks like a genuine advance, and slashing the per-pound cost to put stuff in orbit is the Holy Grail of private space exploration.
But.
Geopolitically speaking, we start building a Beanstalk and all the crazies* start lining up to either bomb it or crash an aircraft into it. It may very well be that a successful strike will not be a global disaster - Edwards' article specifically addresses that concern - but as of right now I remain unconvinced that the hidden costs of counterterrorism procedures would not drive the numbers into the red. To say nothing about actual replacement of a half-constructed and completely sabotaged Beanstalk. And I'm not going to be the only one to have this worry; somebody in the USA or PRC or... damn,that's pretty much it, isn't it? Anyway, there are government officials in either country that are going to point this same point out, probably with real regret.
But, on the bright side, at least it isn't a technical issue anymore. Which is nothing to sneeze at.

UPDATE: Video of the nanotube extrusion here. Jaymiel comments offscreen that this humble video just made the researchers a "veritable assload of money". Funding agencies apparently love videos. Don't ask me: I was a liberal arts undergrad.
