Your statement while technically true has not taken into account scale, infrastructure, and the price per customer to switch. Oil independence is a big deal right now, and we currently have matured the tech to the point that it is feasible for the common man to switch. If you had told the man of the 80s(30 years ago) that he could become oil independent he would be all over it until you told him that it would cost 50000 a car (remember that inflation means that 50k is a far bigger deal at this time) and that the nearest charging station is 70 miles away and because of battery tech at the time he could go about 50 miles on a charge and he would get into his 65cent per gallon vehicle and tell you to go fu¢k yourself. Big oil would still sell their fuel just not to the individual (power plants gotta run off something and plastics still gotta get made) in fact their profit margin would probably be better and more streamlined if they just had to deal with infrastructure than distribute to the masses. The major benefit of the current switch taking place is not complete oil independence but that oil restrictions when they occur will not hurt the common citizen and thus the buffer between the economy and oil prices will be larger. Also since pollution from oil usage will be more centralized air quality can be better monitored/controlled/filtered meaning am overall improvement in the environment.

Agreed
