I'd hate to be in it during a power failure.
The unit only weighs 7 tons but can carry several people
and 13 tons of cargo for a trip of several days duration?
Not possible.
So this elevator "would crawl up a single cable into space over several days." How would people be able to not start up conversations for that long? Would they be allowed to make eye contact or would they have to look up at the ceiling? What if there's a pretty girl on the elevator? And would they pipe in Muzak? These are the things that would have to be worked out.
And would your ears pop?
I'd hate to be in it during a hurricane.
