Observe that, when you use them, you are not writing Lisp, you are writing pure C that just happens to look like Lisp. Those preprocessor macros exist for use in C core only, they are not visible to Elisp, and they happen to be macros for practical reasons of C programming: to always get inlined, in both release and debug builds. Alternative would be of course to implement them as inlined functions and I think they have start to replace some of those preprocessor macros with inlined versions.
