My thinking is of the total amount of material available. Only a couple of places on earth where you can find lithium to mine and neither is very hospitable to human habitation. Peru for one and somewhere in China for the second. Find it, move it, process it to useful product and then you get to manufacture something using that item into a product that will power a mover for convenient conveyance from point A to point B. If you only have enough mineral to build batteries for a quarter to half the demand, then only those who can pay will have access. I'm not saying that we can burn petroleum until all its component parts are in the atmosphere instead of the ground. There had better be technology in the works that uses more than just a single type of mineral or atom with limited supply.
