IMO the paper clarifies the misconceptions about all warp drives. They all need propulsion, for example, to be consistent with physics.

Doesn't that mean that warp drives are not possible? I mean if the device can't produce a driving force why call it a "drive"?

Because Star Trek called their thing a warp drive and that's become the general term for this kind of speculative technology.
