It's a straw man. Reasonable regulations are not going to raise prices by 400%. That's absurd.
Nobody is saying regulate them to death. But maybe, just maybe, don't let the company themselves certify their own aircraft when it comes to matters of safety, required training, etc.
> Regulations are worth the downsides when it's a matter of life and death.
I am in disagreement specifically with this absolute quote.
Regulations may or may not be worth the downsides, even when they save lives. The economic costs matter and should be calculated and a reasonable tradeoff should be made.
You can't make a statement like that and then turn around and complain about my hypothetical 300% price increase for a 900% safety increase.
I strongly disagree with your strong disagree.
