ELI5: if earth does a full rotation of it’s axis in 24 hours in an eastward direction, what (theoretically) prevents a transport system from being built which would go straight up, and then straight back down again in a place west of your origin, taking advantage of the earths rotation?

If you go straight up, you will still retain your momentum you had from being grounded. So going straight up means you keep rotating relatively parralel to Earths surface. You would need to decrease your relative momentum by accelerating against the rotation. There is nothing that can break your rotaion for you, since Earth Athmosphere is rotating too and outside of athmosphere there is nothing to friction against.
