Really? So you don't mind when you buy something marketed as "sterling silver" and you find out later it's really just chrome plated? You're fine with that? You don't think the government has any role in enforcing "truth in advertising" standards?
Re #10 and #12:
Good analogies.
That is a tort, individually, and possibly fraud charges at the State level.
What gives the FedGov the lawful power to regulate that?

Sterling is a term of weight and measure which the government is Constitutionally authorized to regulate. "Extra Virgin" is just a marketing term that is not a guarantee of any weight or measure, just 'grade', like calling something "Premium".
