Its simple by design. Its easiest to get universel consent.

> I fall on the other end of the scale where indirect damage through social/economic/environmental channels can be considered to infringe on liberty. Slander laws, noise ordinances, and non-localized environmental pollution all fall into this category and are eligible to be addressed through regulations which actually improve liberty. However, not being allowed to ask questions does not fall in this category in my opinion.

Sure you can create such contract. But it cannot be called NAP. Otherwise it will lead to miscommunication.
