The energy cost of establishing and maintaining a vacuum in such a large volume, with such an extremely large surface area (the vacuum boundary,) is so exhorbitant as to make this approach utterly foolish. (In Fantasy Land though, you could do it.) Similar engineering economics make magnetic levitation financially untenable as well. If you'd like though, go ahead and complain about reading honest feedback on it, or defend it, or advocate it if you like.
Fools like Daryl Oster are camouflage for the real innovators developing solutions that work.
