Even more basic: who is the "we" that might or might not have free will, whatever that is?

@JasonPSallinger yes, but based on their questions, the OP apparently didn't realize that "Pepsi Free" was a product as opposed to a product name+adjective.

@JasonPSallinger But maybe they didn't understand the joke enough to know what to ask to the google machine

IMO, the benefit of sudo is to make you think when you type sudo, that the command will be run as root. On my own machine, I use NOPASSWD but I still use sudo to make me pay extra attention when I'm doing something as root, and to allow me to avoid opening a root shell when I don't really need to. sudo also has other, IMO, minor benefits (e.g. logging). But sudo provides very little in the way of extra security, as @reed's answer demonstrates.
