Is this what they teach in Con Law class at Harvard?

So former Solicitor General and current Harvard Law School Professor tells us that the federal government could, if it were of a mind to, issue a mandate requiring Americans to buy vegetables, and that such a mandate would pass Constitutional muster (thankfully, the good Professor tells us that they couldn’t actually force us to EAT those vegetables once we’ve bought them. Don’t you feel better now?) Now, Charles Fried is a smart guy. Clearly much smarter than me, because it seems to me that what he’s selling here is just so much nonsense. If the feds can force us to buy vegetables, what can’t they force us to buy? Mets tickets? If Professor Fried’s views are generally representative of what they’re teaching in Con Law at Harvard, there’s little mystery about the sorry state of the legal academy.
