This decision means that the rationale used by the Federal Government in America to control whatever it wants can be used to regulate absolutely every single aspect of American citizens life.
One would have to be on a remote farm with no electricity, phone or Internet, be completely self supporting and do no business with anyone anywhere. Oh, and you'd never be able to travel anywhere at any time, or use any fuel for anything. Then, of course your choices NOT to participate in "interstate commerce" would effect interstate commerce and thus subject you to unlimited Federal control anyway. These guys don't get it and will stop at nothing to consolidate power in the Federal Government. Any limits they may have are purely voluntary (and only temporary).
It's amazing to me just how overt and transparent they now are. There is no longer any attempt to mask or mitigate the appearance of the overreaching power grab from Citizens and States. Except for the "Interstate commerce" and " promote the general welfare" clauses the Constitution is no longer even an issue. They repeatedly flaunt their disregard for it, and denigrate anyone who even brings the fact that it may be a limitation on Federal power. We will need to remain VERY resolute and not get caught up in the frustration of losing a few battles. WE MUST win this war.
