reputation has a problem that it is an "asset" that can be converted to money by abusing it, and unlike a bond which has 1. value outside of the given context, and 2. can be paid out to victims as a form of reimbursement

the best example is a shop closing down. one that wants to earn the most before a permanent shutdown will burn their reputation in a last round of scams, before disappearing. not doing so is illogical, as they can't carry the reputation elsewhere.

and with an anonymous(-ish) marketplace, it becomes hard to tie reputation across identities
