I'm really starting to dig your thoughts regarding unintended consequences of regulation.
Unintended consequences are the result of 'knee-jerk' thinking. Where the 'intervener' thinks that stopping some action will actually work, giving no regard to how humans react to being stopped or restricted. It's a 'surface only - one level of thinking (or actually just not
thinking at all, but reacting - hence 'knee jerk').
One of the best recent examples (other than prohibition) was in the 80's with the 'luxury tax' on yachts and certain cars over $30,000, iirc. The 'rich' stopped buying yachts and any geographical area that had a coastline went into a recession. Some boat builders, sellers went out of business. The 'execs' went to other industries but the 'middle class' and 'lower class' workers - people sanding hulls, doing the grunt work, went on unemployment
insurance and welfare, since relocating wasn't an option. They repealed parts of the tax, but the damage was done. Another 'solution' to help the 'middle class' that did just the opposite. Unfortunately, the 'middle class' and 'poor' almost always fall for the hype and elect or re-elect the knee jerks.
Even with the mortgage crisis, one of the main pushers of the CRA (community reinvestment act - for low to medium income home buyers) and a 'protector' of Freddie Mac and Fannie Mae - Barney Frank said, after the debacle, that 'perhaps some people should be renting instead of buying homes'.
The same will happen if the deeming goes as planned. Even if it results only in taxes to recover cig taxes and MSA money/junk bonds, etc. - either a full black market or a type of fashion clothing/cheap watches 'under-market'
