I would be willing to - would you?
If I borrowed a book or tool from someone - I would be willing to leave some " collateral" with the person until I returned the item.
I have let people borrow things - and never seen them again. I think their memories might have been better if some of THEIR property was also involved.
I am also thinking having some sort of registry might be a good thing. For what I have of other people's things -with name , address, and contact number. And vice versa.
