Honestly if the US doesn’t have a democratically elected president in 4 years its not going to have a president ever, given the last 2 months I doubt there would be anything left to be president of if Trump manages to keep himself in powr for however long he has left to live.
It can be under certain circumstances, its generally desireable for a country to be able to feed itself for example, and being able to produce products yourself is useful when negotiating trade agreements. The problem is when autarky becomes conflated with isolationism.
