They do need a lot less lithium, but we have like 300M cars in the US and only 4M EVs, so unless it's using, like, an ounce of lithium, you'll still have massive sourcing problems. It's also not straightforward (in the US at least) to replace gas taxes with electricity taxes. Electricity is a utility, while gasoline is a good. You can tax goods very easily. Taxing utilities, especially when it comes to "I'm only taxing THIS type of electricity tax" directly violates utility carrier regulations. We had a whole argument over net neutrality, and the foundation of the argument was literally "could you imagine if we charged electricity this way??" So maybe you could do it with registration fees, but that's going to be MUCH harder on lower-income people. It's simple to pay a $.15 tax on your gas tank. It's very difficult to pay an extra $75 on your registration.
