We literally already rotate large structures for amusement.

To be fair, they intentionally rotate slow enough as to have no perceivable g forces.

The example on that list that I had been to most recently is the Westin in Atlanta.

It's 57M in diameter and it's upper floor spins at once every 30 minutes. Plugging that into Mω²r, you end up with 0.0000354084g.

Not exactly the best example.
