The typical way to solve this would be cookies, local storage, or other mechanisms that the site can use.  This is not a use case for a unique, portable user identifier (which the mac address effectively is).

To your point about mac address spoofing: The question isn't whether it's possible, but whether it's a viable way to address the tracking concerns.  Nobody is disputing that it's possible.  But it isn't something people commonly do (or, for that matter, that people commonly should do).
