> Just raises the bar.
Uh, yeah, because you claimed it was a fundamentally weak bar people could walk though. I raised it to illustrate you were actually stepping over it instead.
> It's still a penalty that doesn't relate to the misdeed
They are literally related by cause and effect. Trying to force some broader poetic Hammurabi-style connection is a non-starter, since it means my overdue library book would require a local librarian to break into my home and seize one of my own books as a hostage.
As amusing as that sounds, the abstraction of an overdue-book fine is wayyyy more practical and easier to do in a just and proportionate way. (Especially if all the books I have are from other libraries.)
> hurts different people differently
Which is why fines should be scaled better, like I said in my last post, rather than being fixed sums that some can ignore, like you described in yours.
> The problem is we use money as a form of pain
Anything the transgressor doesn't like is going to be a form of "pain", the least we can do is use something which is both (A) adjustable and (B) reversible.
