Who thinks that an army is unnecessary?

So, we've come to the point where an army is needed to protect the economy. But I believe this is just an unnecessary expense. We need to create not just alliances between countries, but a unified council of Earthlings. And capitalism is already starting to become obsolete. Personally, I advocate for a new order. For example, resources will no longer be part of someone's division, but will belong to a state monopoly. That is, one could say that everything will be state-owned. It will be beneficial to work for the state and it will be beneficial to live in it. But, of course, this does not exclude the market; there will also be mega-corporations, but they will be controlled by the state.
