Another common example of a free market is the universal practice of children swapping baseball cards-the sort of thing where you swap "two Hank Aaron[s]" for "one Willie Mays". The "prices" of the various cards and the exchanges that took place, were based on the relative importance that the kids attached to each baseball player. As one way of annoying liberals we might put the case this way: liberals are supposed to be in favor of any voluntary actions performed, as the famous cliché goes, by "two consenting adults". Yet it is peculiar that while liberals are in favor of any sexual activity engaged in by two consentings adults, when these consenting adults engage in trade or exchange, the liberals step in to harass, cripple, restrict, or prohibit that trade. And yet both the consenting sexual activity and the trade are similar expressions of liberty in action. Both should be favored by any consistent libertarian. But the government, especially a liberal government, habitually steps in to regulate and restrict such trade.
The Boston Tea Party was a political protest by the Sons of Liberty in Boston, Massachusetts, on December 16, 1773. The demonstrators, some disguised as Native Americans, in defiance of the Tea Act of May 10, 1773, destroyed an entire shipment of tea sent by the East India Company. They boarded the ships and threw the chests of tea into Boston Harbor. The British government responded harshly and the episode escalated into the American Revolution. The Tea Party became an iconic event of American history, and since then other political protests such as the Tea Party movement have referred to themselves as historical successors to the Boston protest of 1773.
