That's not quite fair. The Pipistrel Alpha Electro trainer aircraft is FAA certified and in active use by flight schools today. Endurance is very limited due to low battery power density, but it is adequate for basic flight training.
But these other eVTOL designs are probably just too early. It will take several more generations of battery improvements until they become economically viable.
