I'm sure that there will soon be a minimum price for fresh air in smog-choked cities like Beijing. If someone ever does find a way to extract gold from seawater economically, I wonder what kind of economic contractions would occur? As gold goes down people would lose billions while other safe assets like real estate would go through the roof. If we too-heavily rely on crypto-currencies, the same could certainly happen.
