You can write an invalid program in any imaginable number of ways; that's just not an interesting discussion.
What we're discussing is not an invalid program, but what guarantees the type system can provide.
D's current type system guarantees that a T* and a shared(T)* do not point to the same memory location in @safe code.
To get them to point to the same memory location, you've got to dip into @system code, where *you* become responsible for maintaining the guarantees.
