Of course the resulting machine code (not necessarily the compiler)
internally _will_ use a pointer.  But that machine code will also
use base-2 arithmetic, without requiring the programmer to deal in
base-2.  The resulting machine code will use numeric addresses,
while letting the human programmer continue to use symbolic names
for the very same routines.

The purpose of a compiler is to make the relationship of the programmer
to the machine code more trouble-free.
