How do you know you're a person open to reason?

It's only funny if a prerequisite is taken by force. If it's voluntary, it's not funny because it means the oilmen placed a value on their product and them receiving that value from the keyboard maker (usually by payment) represents their contribution. This means the person who uses the oil to create the keyboard has accounted for the ingredient of oil.



I haven't argue against effectiveness or even necessity of law.

How do you place a value on something? What are the mechanics of doing that?

There are theories. Since value is ultimately subjective, one theory is that value can be placed by choice. World economies have performed masterfully when using this theory.
