Does no good when interacting with the standard library, where things like collection methods return null for "not found". All that discipline and organization you're talking about? That's a compiler's job, and if it won't do so, I'll find a language that does. I don't spend much time griping about Java these days though, because I've had many such languages in my arsenal for some time now. Ironically in most of them I use null quite freely because it's now a distinct type and no longer a landmine.

Usually you’re using a lot of Optional and Streams, so the collection method returns null inside a .map() and you don’t need to think about it. To be clear, it is handled by the checkstyle rules at compile time, so you won’t accidentally forget.
