What if no money was exchanged? Say I was the legal owner of a gun and gave it to somebody as a gift, either in Kansas or in any state. No money changed hands. Could the feds have anything to say about that, as things stand? Is that what the Raicha case means - that there doesn’t have to be any money involved?
Yes to your last 2 questions. Clarence Thomas's dissent in Raich:
Respondents Diane Monson and Angel Raich use marijuana that has never been bought or sold, that has never crossed state lines, and that has had no demonstrable effect on the national market for marijuana. If Congress can regulate this under the Commerce Clause, then it can regulate virtually anything–and the Federal Government is no longer one of limited and enumerated powers.
Like I said earlier, drug warriors cheered this decision.
