Show me a few lines of Python that demonstrate the error of the false
inference, please.

When I talk about an object's memory address, I'm not referring to what
might be revealed by gdb, for example. That is, I'm not talking about
the process's virtual address space, nor am I talking about the physical
address on the address bus. I can simply define that the object's memory
address is whatever id() returns.
