It would of course be possible to regulate OceanGate out of business, and I sympathize with the desire to make sure people are sufficiently informed about the risks, which is hard.

But I agree with GP: there is something off about the calls for regulation here. Fundamentally, people should have the right to risk their lives in crazy expeditions to the bottom of the sea or the top of a mountain, and charging someone else money to be taken along does not change that.
