By now everyone who actually reads the news, as opposed to watching Fox News or CNN, is aware that Intrade is currently unable to do business with anyone in the United States. The Commodity Futures Trading Commission is the responsible agency, and has issued two edicts that are often considered separately but together paint a full picture of how fascism works in the United States today.
The first edict is that Intrade cannot offer its services without a license from the United States government. The second edict is that Intrade cannot get a license from the United States government.
It is yet another example of Backdoor Forbiddance, the only thing surprising about it is how blatant it is. One might think that those who rule this country are starting to no longer care about keeping up appearances and fooling people into thinking they are free.
Very little in the United States is actually forbidden. According to the United States government, marijuana is even legal provided one can get the tax stamp for it, the only problem being that nobody can get the tax stamp for it. In many jurisdictions, concealed carry is legal, provided one can get the permit. The catch is that nobody can get the permit. Also in many jurisdictions simple gun ownership is also legal only with a permit, and nobody can get the permit.
Even the IRS has gotten into this act, working to forbid people who are delinquent on their taxes from getting passports. Those people are not forbidden from leaving the country, but they need a passport to do so and they cannot get a passport.
Whatever the motives, and there is actually good analysis of that by Michael S. Rozeff, the action would not have been possible were the economics and politics of the United States so far descended into the fascist model. Anything is allowed, with a permit, but no permits are given if the leaders do not like the activity in question.
