The trick with a space elevator is that the cable needs to be very thin. The material needs to be strong. That’s just two reasons why we’re still far from putting that to any real use.
I don’t think having a small line through our atmosphere will slowly poison us. The extra radiation that would make it through is probably a rounding error. The material would have to be such that it doesn’t attract radiation. And even if we discovered that this could be a problem, if we have become smart enough to build this space elevator, we’ll probably be smart enough to figure out a way to filter it out.



The benefit it affords us is being able to easily write our name into snow. That can be pleasurable under certain conditions, mostly alcohol-infused ones. Beyond that the only pleasure I could possibly see is the relief to have made it to a toilet and not having pissed your pants when you were dying for a one. The length of the urethra is not relevant in that case. I’ve personally never pissed and thought the experience was physically pleasing - beyond what I’ve already mentioned.
