I guess you might be able to get around this problem if the vehicle can take off and land on a land based airstrip and then stay at 10m over the water. Otherwise that is a crippling limitation since you not only need the ocean to be relatively calm when taking off, but also when landing.
Usually these planes take off and land on rivers, bays, and other protected shores with few waves.
For FAA purposes this is 100% not a plane.
Regulatory arbitrage is part of the value.
Physics doesn’t care about regulations though. I hope the people who fly these are certified to fly passengers.
