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.
Wow. History much?
Prohibition = booze supply increased, price went way down
WWII parachute material = supply of nylon stockings went up, price stayed the same
War on Pot = supply increased
massively, price to get high went down (price per weight went up, but quality went through the roof)
War on file sharing = supply dwarfed demand, price went free
War on porn
War on etc., etc., etc.
EDIT:
silk stockings... * sigh *
Oh - and war on literacy (Medieval Era) = printing press
Restricting things that mass numbers of people want
NEVER
EVER
Works.
