Let me get this straight, your idea of a valid counter to my assertion that the federal government has improperly usurped authority nowhere provided under the Constution, is to reference a case involving even more egregious usurpation by the federal government? Brilliant!
The "commerce Clause" is NOT to provide any sort of over-arching authority to ply anything that might be even remotely associated with interstate commerce with regulation, taxation, and mandate, but rather
only a vague authority to "regularize" or "make regular" that interstate commerce to so as to prohibit any sort of imbalance between the states, and thereby preclude a cause for warfare among the states.
There's another case that made the news recently, where this criminal federal government compounds it corruption THREE-fold, by the Department of Injustice not only using the corrupted "commerce clause" but also federal laws being applicable to the states at all, and the corrupt hate crime laws, that the federal government has no legitimate authority to legislate either. In this case a handful of Amish persons were prosecuted under federal hate crime laws, for having used trimmers to cut the hair and beards of other Amish. And the means the federal government claimed it had this authority? The fact that those trimmers were manufactured in one state, and used in another, thereby having crossed state boundaries.
This is specifically not the terms by which the founders referenced the Commerce Clause,
In point of fact, just the case you cite, and those like it, are cause for Americans to take up arms, and overthrow an illegitimate and tyrannous government, using whatever force is necessary. Perhaps you've noticed the unprecedented arming of citizens going on, and the deliberate preparations of the federal government itself to institute martial law, while simultaneously trying to dry up the market on munitions, and illegitimately curtail the right to keep and bear arms, recognized by positive mandate, without any caveat whatsoever.
None of this is good thing, but it is a necessary thing; quite clearly you need to understand precisely why it is occurring.
