I also wonder if somehow we're trying to seriously reduce advertising what that does to land of the internet where the users of the internet seem to choose / want "free" advertising based products. I'm not convinced folks just suddenly pay and upending that entire economy maybe a serious net negative.
I was just talking with some friends recently about an instance of this: distilling, which is still federally illegal in the US for the primary reason that it provides a lot of tax income if you charge for licenses and tax sales, which is incredibly frustrating because it's easy and safe to make yourself high-quality liquors at a fraction of the price that you'd pay at the store and have a fun hobby to boot.
(pedants: please don't bring up safety issues - it's trivial to realize with five minutes and internet access that distilling isn't significantly less safe than many other unregulated activities in the world as a whole)
