Not including null has consequences, you can't just keep your language as it is, remove null and say you're done.

What's the default value for a pointer in the absence of null? You can force the developer to assign a value to each and every pointer at the moment they are declared, rather than rely on a default value (and the same thing for every composite type containing a pointer), but then you must include some sort of ternary operator when initialization depends on some condition, but then you cannot be sure your ternary operator won't be abused, etc.

You can also go the Haskell way, and have a `None` value but force the user to be in a branch where you know for sure your pointer is not null/None before dereferencing it (via pattern matching or not). But then again you end up with a very different language, which will not necessarily be a better fit to the problem you are trying to solve (fast compile times, easy to make new programmers productive, etc.).




But null pointers are not really a problem in Go, aren't they? The problem only exists in lower level languages.

Go, as a language, is a pretty good one. It's Go's standard library that's not, especially "net" and other packages involving I/O.
