Well yes... That is why we allow them check that we operate to safety standards. Notice I didn't say if he kept them on his land, I said "If he disposed of such hazards properly." Leaving it on your own land was purely your concept. Disposing of it properly would mean in a way condoned by the federal government This would INCLUDE air management. Sure... you can't exactly "dispose" of smoke and smog... but you can operate in the way that produces the least of it. All of that, I believe, would be valid for the government to enforce.
Yet still... you did not answer my question. So long as I followed every guideline that they provided for in terms of a "clean and safe" factory... should it matter what I produce? I mean... so long as I'm meeting the guidelines and dealing about it in a responsible way... what difference would it make what I produce?
And let's say it is NOT a factory. Let's say it is a farm. Two farms, actually. And let's compare them side-by-side. Get up early, work the fields. Tend to the animals, AND the homestead. Harvest your crop(s) after a long, hard season of work and enjoy it. Only... the feds come around and say that the owner of Farm B has to pull all his crops, even though he acted no differently than did the owner of Farm A. The difference, then? Farm B grew marijuana, Farm A grew corn. The only people affected by the choice in crop? The owners of the farm. Farmer B obviously can't go sell his goods like Farmer A could... but the only thing that this equates to is Farmer B not having the money that Farmer A would. But in this instance... neither farmer affected anyone but themselves. No pollution issues, no anything and would it be right, at this time, for the federal government to step in and act as they did?
