It's also something that could be handled by an excel spreadsheet as long as the budget was set. Providing a forum for the states to argue about issues is an actually useful and non-redundant thing that the federal government does - setting the budget wouldn't work without it. The facilitation of interstate commerce through a federated union is a great thing. A coordinated foreign policy and unified military is more effective and probably more efficient. The federal government isn't useless or lacking any impact at all on my life, but the state and local governments are far, far more involved in "getting the things I depend on done", and many of the things federal government does could probably be done without a federal government or with much less of one.
