The common thread should be obvious: It’s not difficult to act in a libertarian manner. It’s how almost all of us were taught to behave from our very earliest experiences with other people.

One lesson almost universally imposed on small children, though, is less helpful. That is “You have to share.”

 

If you are given no choice in how your property is used by another person, it isn’t “sharing.”

It can be a considerate thing to decide to let someone else use your property. Usually. It can’t be done under coercion or it isn’t “sharing,” no matter what the parents may call it.
