My sense (somewhat out of date) is that most flying car people consider VTOL and hovering to be fundamental requirements of the format. Helicopters (and other aircraft capable of VTOL and hovering) substantially mitigate both of these issues.
If we're talking about fixed-wing, runway takeoff aircraft, then I absolutely agree with you. If we're not, I'm somewhat (but not highly) confident that coordinating these vehicles will be the long pole re: capacity. That's mostly because it's a really long pole. We haven't developed distributed actor algorithms for this the way we have for cars, it's unclear if this is actually possible, and there's no way the current way of doing ATC can handle the load that even 1% of upper middle class commuters could create.
