You didn't ask that question of legality's influence on the market price of the SAM.
But in this case, it isn't the the question of legality that makes it too expensive for the common man to own.
Poor, poor example.
Maybe you should think about what would happen if tobacco products were made illegal. Think about the black market supply chain that would spring up. Think about the increased prices, the jail sentences, the turf wars, the bribes, the corrupted police and judicial systems.
That's what we had with alcohol prohibition and that's what we have with marijuana prohibition.
And it seems that you support all of that.
I didn't really care about market price, because it is irrelevant. Legality would make SAMs easier to obtain, no "ifs," "ands," or "buts" about it. And once you start talking about restrictions and regulations you are indicating control measures, and they you are on my side of this discussion.
And do yourself a favor and see if you can go one libertarian thread without bringing up Prohibition. Prohibition took place 70 years ago, and is no longer a useful tool in for analysing modern society or law enforcement techniques.
And while we're at it, see if you can keep your post focused to one general topic. Post as often as you like, but this constant HTML editing is tiresome.
