The supposed use doesn't matter. Players were given a piece of functionality; everyone uses it the way they like.

Off the top of my head: food supplies. I'm not exactly comfortable carrying pig heads with me all the time, first because they are quite heavy and second, the only place where I can use them now is the Camp. If you don't mind that, good for you; but I'm pretty sure this QoL improvement will be greeted by many, myself included.

A bit of a real world story regarding proposed and actual use, if you are interested:

When Thomas Edison filed a patent for his newly invented phonograph, he listed 10 possible applications for the device in an article published by North American Review in June 1878. Here they are:

1. Letter writing and all kinds of dictation without the aid of a stenographer.
2. Phonographic books, which will speak to blind people without effort on their part.
3. The teaching of elocution.
4. Reproduction of music.
5. The "Family Record"--a registry of sayings, reminiscences, etc., by members of a family in their own voices, and of the last words of dying persons.
6. Music-boxes and toys.
7. Clocks that should announce in articulate speech the time for going home, going to meals, etc.
8. The preservation of languages by exact reproduction of the manner of pronouncing.
9. Educational purposes; such as preserving the explanantions made by a teacher, so that the pupil can refer to them at any moment, and spelling or other lessons placed upon the phonograph for convenience in committing to memory.
10. Connection with the telephone, so as to make that instrument an auxiliary in the transmission of permanent and invaluable records, instead of being the recipient of momentary and fleeting communication.

The only application that the devices descended from his invention are currently used for is #4. Moreover, Edison himself very much opposed this idea at first, which is understandable considering that he tried to make the emphasis of his invention on its recording capabilities, not the reproductive ones. Besides, the phonograph in its initial form was plagued by numerous shortcomings: the cylindrical recordings were only 2 minutes long, and initially there was no way to mass-produce them.

The moral of the story is: no matter what you think something should be used for, the eventual common usage is bound to be something different.
