Returning a vehicle to a bank that someone has stopped paying for isn't exactly harm. If banks were unable to get vehicles back, people with bad credit would have a much harder time getting a vehicle in the first place.

There are A LOT of throwaways talking about repossessing cars in this comment. that's a little weird. Guess I struck a nerve at some company.

Who else would buy it? What use exists for this data that isn't harmful to society?

Repossessing collateral on a secured loan is not a service designed to cause harm.
