So if we took away 1% of that 1000x it's own weight it would be able to lift it? It can't. It will never be able to. Only thing I got out of my engineering dynamics class - ropes don't lift. Well, that and jokes about couple moments.

A lift is not a hold. A human can hold a ton of weight against gravity, but that's not them lifting it. See the squat. You can put a huge amount of weight on your back compared to the amount you can actually move. If you put them on an escalator, they could probably even move a distance with it. But that isn't them lifting it that distance.

A human can hold several loaded shipping containers stacked upon each other against gravity.

The human will be very flat and leaking all over, but it will be holding the containers.

as someone who stalls out at the midpoint of a squat coming up very often i can tell you that locking your knees with weight on your back is not holding anything - it's putting your posterior chain under compression. my point was that something like a barbell hold (like this http://www.myfitnessstudio.co.uk/wp-content/uploads/barbell-...) is just as hard as just curling.
