An underappreciated benefit of rotavators: reentry

So, you're in space and you want to get back to Earth. You'd like to NOT have to do an atmospheric re-entry with massive heating and plasma windows and all that. Seems scary and a big chance for things to go wrong.

With a rotavator, the worst of that deceleration will be handled by tension on the cord rather than atmospheric braking. However much spinning velocity you have (plus the lower orbital speed from having a high center of mass) will be subtracted off your orbital reentry.

And unlike using one to get up INTO space, there's no difficulty in synchronizing a meetup. You can hitch up in orbit, near its center of mass - that'll be easy - and then work your way down the cord. On the actual descent, just get down to a convenient altitude and speed, and let go at some time in a reasonable window.
