There are obvious limits. One of them is that you need to invest, and not just spend money on groceries, as people say. If you don't invest in education, your society will grow poorer. That's straightforward. If you don't invest in health, it will cost you a fortune in the long run. If you don't give yourself the tools to support the development of your national economy, you won't develop it.
In the long run, how do we generate more wealth? It isn't by running a country like an accountant. It's by investing intelligently. I agree that we shouldn't spend unnecessarily and that the budget isn't unlimited. That's obvious.
