Picking and choosing which laws to obey is extremely simple. If it involves the initiation of force to harm another non-consenting person or to steal or damage their property, personally or via an intermediary, it is a crime, and laws forbidding it are valid. Otherwise, not.
Note that this means that the following are invalid: every gun law, every tax law, every drug law, every licensing and registration law, every law that criminalizes any behavior not described by the paragraph above.
Furthermore, every person involved in making and enforcing any such invalid law is himself a criminal. Every arrest for such a law is false arrest, kidnapping by another name, hence a capital crime, punishable by life imprisonment or death.
That's what I'm teaching my two kids (11 and 6). And my son will very soon be big enough to help shoot the bastards, should they ever attempt to take our guns away.
