I’m a pretty progressive guy and I don’t think there’s much in here to disagree with. The only nit I would pick is that inertia isn’t a great argument to keep things the way they are. That is, “we’ve always done it this way” isn’t a great reason to do anything.
Your framing of conservatism is in line with the Eisenhower era when we weren’t linked into this existential crisis about the concept of governance. But for the last twenty years (at least) the American right has been against the very idea that the government should govern.
The left is trying to argue about who it should serve, taking its existence as a precondition, and the right is trying to dismantle it without regard for who it serves. As a result, we’re pretty much irrecoverably talking past each other.
