Sure. But you’ll find there are a number of controlled real-world tests and studies to quantify those public based studies. And one of the last large-scale, controlled tests of UAM using helicopters validated the concept but proved noise was the principal deterrent to helicopter use. It was this noise result that led NASA to develop a new electric-based propulsion/control concept called Distributed Electric Propulsion (DEP). Which in turn became the foundation for the e-aviation industry to include eVTOLs. Without DEP none of this would be possible.

Turns out hybrid helicopter seems to be the next hype after evtols fully exhibits their short coming.
The hybrid market is being driven more by the turbo-generator advances than anything else. But on the eVTOL side, Joby and Archer are in the final certification phases and the initial flight programs in NYC, Chicago, and LA have the infrastructure in place. So you won’t have long to wait to see if your theory is correct.

Electra is using a different blown-wing concept for their eSTOL. They’re currently flying the development prototype and finalizing the pre-production model.
