It is true that removing and demonetising Nazi content wouldn’t make the problem of Nazis go away. It would just be moved to dark corners of the internet where the majority of people would never find it, and its presence on dodgy-looking websites combined with its absence on major platforms would contribute to a general sense that being a Nazi isn’t something that’s accepted in wider society. Even without entirely making the problem go away, the problem is substantially reduced when it isn’t normalised.
