People are often angry with each other and eager to hurt each other in any legal way available. (Ask your friendly neighborhood divorce lawyer for their stories.) This sort "anyone can take your stuff if they're irrational enough" would be very easy to exploit to make someone's life miserable. And the problem only gets worse if you imagine a normal person making a very rich person angry.

Thank you, you said it better than me. Any system where anyone can take someone's stuff without their consent, even for a price, would never work.

They see you have a good pan and want one that's the same. Buying yours is less effort than going to the shops and faster than ordering one.

Obviously social decorum would usually prevent this scenario, but the fear of possibility remains.

Maybe that firing pan is owned by a rockstar ?
