> When the price declines those people can (and do) buy the oil westerners aren't using.

You're missing that the supply drops as well since it is not economical to produce the same amount of oil as before at a lower price.

As long as the supply curve does not change (and nothing about EV usage changes the supply side here), a reduction in demand leads to lower consumption.

Edit: And in addition, your chart doesn't show anything like you purport it to show. By your claim, oil consumption by non-Western countries should have been drastically higher in 2000-2007 when oil prices were lower than they are today. Yet the opposite is true.

Oil consumption is up over time, including in non-Western countries, but that was driven by organic changes in demand, not changes in supply. Switching to EVs would act as a reduction in demand and therefore reduce overall oil usage, at least as compared to a world where vehicle transport required ICE vehicles.
