They are though - we know how to build high capacity transmission, we know how to build complex dispatch control systems, we know how to build energy storage. All we need is the money and factories and brains and hands to build a lot more of them. All that requires is powerful entities to decide it's important - i.e. politics.
Politics is not powerful entities. Do you mean politicians, or governments?
Either way this is a category error. Tesla needs those things and used venture capital. A correct thought would be: governments are one way to do this.
