Obligatory Library Socialism Link: https://librarysocialism.org/

In the simplest terms, the right of usufruct means you can use things, but you cannot deny them to others when you're not using them, and you do not have the right to destroy them to prevent others from using them. So, for example, the farmer is welcome to grow crops on a given plot of land - but if they choose not to, somebody else can use the land.

Given this, it's easy to see that this principle already exists in public libraries. You can borrow a book to help you start a business, but you can't prevent others from reading it after you - or threaten to destroy the book unless you receive the profits of the next reader's business. You can hold the book exclusively (of other library patrons), but only temporarily.
