This doesn't pass the smell test, though. The premium would take care of that. You've told them you have a pillow, and that you want it insured for $1M. They could easily look at it and go "hm, this is worth $10", and give you a absurd premium of $999,900 in exchange for your absurd valuation. So happy accidents won't be worth it anymore. What's wrong with just letting the premium take care of it?
