Yeah. You aren't allowed to set up a life insurance policy on someone else's life, or a fire insurance policy on someone else's home. For obvious reasons. But buying an event contract that pays if someone dies or someone's house burns down is fine?
being pedantic here but > You aren't allowed to set up a life insurance policy on someone else's life, or a fire insurance policy on someone else's home This isn't really true. Lots of people take out life insurance on others as a hedge for many reasons, small business partner is one. Same fire insurance, we had a case where someone pledged a building as collateral and we took out separate fire insurance on the build…
If you wanted to correct a misconception, you should provide a better, more complete understanding, not just express frustration about a misconception that doesn't even exist outside of an uncharitable reading.
In this case, that means refining the point to the more accurate model, that you need an insurable interest -- i.e. reason you don't want the event to happen, even knowing you'd get a payout[1]. Your counterexamples only work as such because that exists![2] If you want to fix all the people who don't have your superior understanding, that would have been a great way to help them out.
>I'm not sure where this false premise started but alot of people believe it.
It exists because it's approximately true: you can't get insurance on 99.99999% of buildings in the world because you have no insurable interest in them. And any time someone could correct that false premise, they probably just complain rather than providing the complete understanding -- exactly the choice you just made here.
[1] IMO, this is the natural dividing line between gambling and insurance https://news.ycombinator.com/item?id=13916088
[2] Edit: And in your building collateral example, the policy would prevent you from double dipping -- getting both the building and the full payout.
