OK. (I would likely argue against a lot of fines. I was able to come up with one, though.)
The local library is financed with local tax dollars. A person in the community may have a library card and may check out books/DVD's, etc. at no cost. However, the person must pay a fine if he/she keeps the book/DVD for longer than the established time-frame without renewing it.
In this case, it is acceptable to me for the city (or county) to apply a fine for an over-due item, even if I would not like to pay a fine. It a form of a punishment, or incentive for timely return, that a fine is imposed for late items. That practise keeps the books/DVD's available on a regular basis for others to enjoy. It is ok for the city/county to have the library collect these fines, because they are used as part of the cost of operating the library.
However, it would not be OK for me, personally, to attempt to collect a fine from another person, because I have nothing to do with the operation of the library -- except that I pay taxes and have benefit from the use of it (and have a moral obligation to respect its property, as public property.) I have no right to personal financial gain from the occurrence of another person keeping an item for an extended period of time.
If I were to take it upon myself to do such a thing, I may either deny the library the fines due to it if I take it for myself, or I may create an injustice of a situation where the other person is fined twice, by me and by the library. I see nothing about this scenario that would justify me (as an individual) applying a fine to another individual.
