I'm sorry, but this is just pure nonsense. ASM has nothing to do with
anything, being just a textual representation of hardware instructions.
I take it you argue that conventional hardware doesn't provide dedicated
instructions for checking pointer validity, but you have been told that
such hardware does exist and is deemed useful.

And C++ is not ASM on steroids, mind you. While it does allow quite
low-level code, if you want it, it does provide its own abstractions and
rules that allow it to be portable across variety of hardware. In
particular, pointers, as they are defined in C++, are distinct from
integers, which is something low-level programmers tend to forget at times.
