Moderation in the pursuit of a better world is no virtue. As a consequentialist, I disagree with your premise that subverting bad laws is unethical behavior.
But then, we need to define what is a bad law. In this case I don't considering selling drugs, guns and illegal substances online ethical by any means. Not to mention the tax evasion which hurts all of us.
So, what does "unethical" mean in this context? Can be universally measured somehow?
