The obvious solution is a monorail that you balance upside down on. Since none of it is, as Vman455 points out, real.
I don't think the mechanics or the physics are impossible. Achieving silly gear ratios is easy. There's a guy on youtube that invented the worlds most geared down gearbox. I forget the ratio, but a cordless drill wouldn't turn it a full rotation in something like billions of years.

Perhaps the hard part would be creating bearings that can withstand rotating at whatever is required to travel at ~4000 MPH with no air to cool them.

If I understand correctly, inverted in a tube you could experience 1 moon G if you traveled ~8,000 MPH.

Seems there's an awkward transition speed at which you float weightless, unable to steer or otherwise maneuver.

The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary. -H.L Mencken.
