The problem is these elements do not exist at quantities and production levels like oil did/does.
There is a reason they are mined in only a handful of countries in the world.
Furthermore, are these materials only produced in those countries because they literally do not exist anywhere else, or is it only produced in those countries because they're the only sources it is currently economical to extract?
These distinctions matter

Elements exist everywhere, you can find gold in seawater.
They are produced in those countries because that's where the deposits are concentrated in levels that make it worthwhile for mining.
I just don't see mass electric cars being feasible with today's technology. A slight increase in % of elec cars would lead to millions of tons of new raw materials needed that naturally only exist at 20 ppm levels. Then you have to consider the demand that would place on the power grids and plants.
We need new technology. I am hoping something can be done with aluminum considering how abundant it is.
