Nothing stops you from using pure function components, and you should where possible. But eventually, you need to hold state somewhere. You don't need to put it in your components, but you do need to deal with it. If anything, hooks are a nice middle ground where the behaviour becomes declarative.
My personal opinion is that state should be contained in some sort of class or data structure, separate from functional architectures where the notion of state is generally avoided. So my usual suggestion would be to use either a class component (or redux or insert favorite state mgmt solution here) for your state, and then inject the state as props to your function components
That's fine, you can use React's Context API and reducers just like Redux, for which the useContext and useReducer hooks exist. Then it's just like Redux, inject a Provider and Consumer and you're good to go.
