For Individual, Local, Regional, and National Security Reasons. If an individual is not beholden to an external entity for fuel sources for vehicles (&homes) then they are inherently more secure. This applies to Local, Regional, and National scopes. At the national level we are not beholden to hydrocarbon producers, their lobbying, their subsidies, their unrealized environmental side effects, nor any other national actors, thus making every nation leveraging EVs more secure and self reliant.
This is only true if all of the key components of electric cars are also locally available. Producing electric cars (especially batteries) requires lots of rare materials, not all of which are available in quantity in the US.
