Things aren't unconditionally necessary except in modal logic. In the real world things are conditionally necessary. Clean code is necessary... for ongoing development. Clean code is necessary... to allow developers to onboard quickly. Clean code is necessary... for reducing the cognitive overhead and avoiding mistakes. Unfortunately without stating these assumptions it's impossible to prioritize and be rational about development. It provides no guidance. Should we drop everything we're doing and "clean up" the code? Is it even worth investing in? These are questions that have different answers depending on the assumptions and simply saying it's "necessary" is insufficient.
