It doesn’t matter what you think. Governments are expected and set up to do much more than that around the world and that’s because that’s what their intents are. It’s not just those three things. If what you said was true, we’d have had no meaningful progress on anything.

I think you’re misunderstanding the person you’re talking to. They are just saying that anything that can’t do those 3 things is not a government.
There are a lot of things that collapse a government if not done that’s not one of those three things, though. Like educating its people. Especially that one for a democratic government, in actual fact.
