If these e-VTOL aircraft get used for air taxi service at all it's going to be for short hops in denser urban areas. Not in rural areas where people have acres of open land.
Go watch one of JoeBen's interviews. His original inspiration for the company was making something that could make where he grew up in the redwoods of the Santa Cruz mountains more accessible. His stated long term vision is vertiports embedded in communities. In the short term, I agree that they're going to start in denser areas.
