Not to mention from a human rights perspective, it's not just easier to obtain sodium than lithium but also more humane.
There is an industry for ethically-sourced materials, and even if this doesn't completely replace lithium it can still significantly reduce the amount needed to meet demand, which can also encourage more ethical practices in that supply chain too, such as sourcing it from areas with stronger labor laws.
