This has always been functionally impossible at the current understanding of science, even with superconductors. There's nothing to "push off of", unless you can invent literal anti-gravity technology, which afaik, is impossible.

Sure, the Earth has a magnetic field, but it can barely move a compass needle. It can't even lift a single gram of weight, much less some dude and a board.

You need a rocket in the bottom to be able to fly around freely. Or you'd be limited to keeping it inside a special area made just for it, using electromagnets.

Just replace all roads, sidewalks, and building interior floors with magnets. Easy.
