 | Since there's hardly any atmosphere, and damn little gravity as you
leave the moon, all that we're dealing with is mass and velocity.
However, having that tether represents an alternative method of using
crawlers that can travel as fast or as slow as the task demands, then
magnetic or even physical friction onto the tether as to stop at any
given floor. After all, we're only talking 64,000 km, and that's only
64,000 of those individual floor buttons.
Remember that the LSE-CM/ISS comes with a rather nifty tether dipole
element, thereby we've got terawatts of energy to burn. Thus our
"Emergency Stop Button" is based upon thrusters as well as upon the
plan-B of available friction of the tether that can be configured as
robust and full of surface area as need be.
Actually several tethers may ultimately function on behalf of a
counterbalance, by which the falling mass can be gradually ejected or
released entirely. I assume that magnetic fields still function in
space, so what's so complex about using a moving stream of magnetic
fields in order to create whatever retro-thrust energy for breaking the
velocity of going either way.

Not near the Moon, you don't. The solar wind isn't that strong, nor is the
magnetic field of the Earth that far out.
