To understand what WikiLeaks has done, we must understand economic cause and effect. Let us begin with a comparable market: the market for gambling.
Governments have laws against gambling. Why? The justification is moral principles. This reason is less persuasive once the government sets up state lotteries and also licenses taxable gambling, such as horse racing. The real reason is the governments want to monopolize the vice. They expect greater tax revenues.
Governments arrest bookies. But bookies are merely providers of the service. The source of demand is the individual gambler, the guy who is placing the bets. The infrastructure that delivers the service is surely basic to the process, but it is the individual citizen who is the prime mover. Why? He is paying for it.
Want to understand the process? Follow the money. It ends with the customer.
