This is actually a pretty interesting matter. Sovereign individuals do indeed have a right to conduct affairs, including economic, necessary to prosecute their lives. Government does not have a right to prevent them from undertaking economic activity, and there is no compelling need for public safety measures that necessitates grading butter. As the rise of decentralized production begins to flood markets with various products competing with industrial producers, I expect government to be used as a weapon by industry to prevent that competition.

Perhaps in the future I won't need a government license to wash your hair for pay. It's long past time such barriers to economic activity were smashed.

Thanks!
