Haven't the fat cats already done that with their ETF scams, commodity "exchanges", and leveraged contracts? They swap counterfeit gold and silver paper/electrons back and forth while hardly being bothered with the underlying asset allegedly being "traded". Obviously if an "unlicensed" individual or group of individuals were to do these things they'd quickly be kidnapped and stashed away in a rape cage, but so called "market makers" do these things on a daily basis and call it a "service".
