I could get gas to $2 a gallon in the US, I could do it within a few weeks instead of the years it would take Bachman to have any credible effort.
If I ban approx 30% of the daily traffic. I could get gasoline down to $2 a gallon. Any attempt in trying to get gas down using supply will take years. Changing demand would be instantanous. Or If I dont want to ban driving, I could tank the economy. Causing 30% of the current drivers to stop driving. A third option is to revalue the USD. Have every current USD turned into to be replaced with 0.5 NUSD. A common thing in Banana republics
