Good points, but not necessarily eternal truths. I suspect you could use magnetic fields to strengthen the cable. Of course, that would collapse if the power failed. But perhaps there are other alternatives that nobody has thought of.
Still, my favorite skyhook is the PinWheel, though it needs a hefty mass in a fairly low orbit (as well as long arms that reach into the stratosphere). But you need to lower as much mass as you raise (on the average) or the orbit decays.
