Regarding the third point, for bitcoin to be an analog to gold we must keep in mind that gold is universally known and valued. If bitcoin prematurely choked off its own growth and abandoned efforts to mainstream it, I suspect it would slowly wither and die as competing altcoins rose to take its place as an everyday, mainstream cryptocurrency.

The current price of bitcoin is based largely on expectations of future growth. Choke off that growth and I suspect a large portion of its current valuation will evaporate.
