We have decades of experience to learn from in the aviation industry, that is what we should be iterating on and benchmarking against.
Making a new type of aircraft that is significantly more dangerous and requires significantly less training (so it is unrealistic to expect the consumer to understand the risk) is just valuing profits over human lives - full stop.
Are you still okay with unsafe flying machines when they start falling out of the sky and killing people on the ground? As mentioned previously, these aren't even supposed to require a pilot's license, so you can't expect the customer to be trained like a pilot.
The FAA rules are written in blood. If people want to experiment with new types of aircraft responsibly, that's fine! There is even a specific process for that, it's called an experimental certification.

But selling these things to untrained consumers is just completely, utterly, reprehensibly irresponsible. That's probably why Kitty Hawk returned deposits - they realized the machines just weren't safe enough to sell to people.
