If production of certain goods/services are restricted, supply will decrease and price will go up. If an artificial incentive is created to boost demand for a good/service, demand will increase and price will go up. If Bitcoin use is restricted, supply will stay the same and demand will decrease. That will cause the price to go down.

Anyway, the CFTC is only regulating financial instruments related to Bitcoin, not Bitcoin itself, so it's not a problem. I just wanted to demonstrate that the OP doesn't understand basic economics.
