It's foolish to think ASLR only prevents stack smashes - it also prevents unlink-style attacks via heap overflows and use-after-frees, data overflows into point

It's foolish to think ASLR only prevents stack smashes - it also prevents unlink-style attacks via heap overflows and use-after-frees, data overflows into pointers and other segments, and many other vectors. Yes, it is a mitigation strategy that wouldn't exist in an ideal world. But we have to do best with what we have, and security takes a very pragmatic approach at this.
