usufruct
So... reading the Wikipedia article on it for more info, it doesn't seem to place any limits on what you can own. It simply lets you makes allowances for others to use something of yours. It doesn't seem to mention forfeiting unused property in the least.
It's basically just being a landlord, but with other stuff, no? I'm not following how this isn't corruptible unless there's something I'm missing.
So you missed out on the series finale where it's a 45-minute flashback to Bigfoot barebacking Scully?
Edit: I apologize for the weird boner I just gave someone.
