1) The loss of proper jury trials. See: http://www.fija.org and http://www.isil.org/resources/lit/history-jury-null.html 2) The loss of habeas corpus, via the Patriot Act and NDAA 3) The loss of medical freedom and its corresponding free market of innovation in 1910, with the AMA, FDA, and later, DEA 4) The barriers to entry into the market, caused by licensing of all sorts.
5) Also, the reduction in capital caused by the Federal Reserve, IRS, and fiat currency. 6) Ballot access restrictions and impediments. 7) Food handling laws that require a human to be present, so robotic vendors cannot easily market their wares etc...

These are all chains that bind intelligent people. These are all barriers to unlimited progress. I've written more about them, but my karma is too low for me to post here. I find that to be a stupid impediment/barrier to entry to the market that will likely drive me away, rather than have me expend the effort necessary to "ramp up."

BTW: I completely agree with the author, and think his piece is one of the best things I've ever read. Particularly the last two paragraphs.

Peace.
