The technical term is that you must have an “insurable interest” in what you insure. Both of your examples are people protecting their insurable interest. Ownership is the most common insurable interest, but there are many other ways to have one.
This is done because the insurance company wants you to prefer that the covered event doesn’t happen, which avoids some conflicts of interest.
These prediction market events don’t have the usual insurance interests involved.
Even if you have an insurable interest, moral hazard may arise - acting recklessly or other abuse, while knowing you are insured/covered. Somewhat similar to friendly fraud in retail/ecommerce.

Yep, we're in full agreement here
Unless you short the property. Essentially, sell it now on the bet that it will drop in value later. Then it burns down and you repurchase the vacant lot and return the property to the original owner.
Evil, but most everything in real estate is evil.
And that's exactly the problem with Polymarket and such, it gives an incentive to be destructive because that's easy. Entropy is easy.
With an insurance this trick won't work, because the insurance company will notice what you are doing. Polymarket doesn't care.

This has worked well millions of times (and occasionally failed too with people ending in prison or with huge fines). Where I can agree however is that Polymarket makes that much easier.
