* Can you stop a guy from making experimental taco flavored cereal at home then delivering it to people who ordered it online?* Yes, quite easily. For the guy selling tacos, possibly prison, but more likely fines. And since we're likely dealing with interstate taco sales, these fines can be enforced via wage garnishment and may even survive a bankruptcy. For the startup...massive civil lawsuits. That corprate entity they formed? Not going to help them if they are undercapitalized with inadequate insurance or financial reserves, since the corporate veil piercing doctrine will allow plaintiffs to go after the owners and investors personally. I don't think that the government should be this zealous in enforcing these regulations, but there's a good chance that they will try to make a few examples out of a few unlucky startups/individuals to minimize violations.
