Also, as a matter of practicality given the scope of commerce, it is really practical to have 50 states individually inspecting, for example, California produce rather than this being done under the auspices of the USDA?
The problem with "Constitutional purity" is that we've strayed so far from "original intent" that one needs to work within the system as it, rather than how one wishes it might or should be. We're not going back to a rural/farming economy and just laws need to respect not just the past, but both current reality as well as overall societal needs. Being a realist is not inconsistent with being a conservative. It's all about being consistent with an overall guiding philosophy that seeks to maximize individual liberty while ensuring the common good.
How far had the colonies gone under despotic England? Had they also gone “too far” to break English totalitarian hold? I don’t think so.
There are many ways America can experience a rebirth of freedom and recovery of the Constitution as the Law of the Land. One important way is state nullification of unconstitutional federal acts, as many have just now against the unconstitutional federal act of allowing the clear and present threat of an enemy invasion.
I think we are going to see a turn around and a reinstatement of the Constitution as Ruler OVER the feds. The fight for freedom never dies. You either fight and win, fight and die (that’s OK too), or give up and give in to slavery. Let’s hope there’s enough of us who will never accept that last choice.
