That’s certainly a valid opinion, but I think you run into a problem when the word “tyrannical” is supposed to apply to taking measures to limit the flavors being added to a highly addictive and health damaging substance, and the government of North Korea.

Edit: Also, the government does not currently have the regulatory authority to ban tobacco. It can set limits on additives and regulate nicotine content, and it has the ability to regulate the format and forums of advertising campaigns, and can set restrictions on purchase age or require health warnings, but each one of those things is fought tooth and nail by the tobacco industry in the courts.
