Very interesting! I've started reading the 3-Lisp paper [1] and it's a lot of fun.
I'm not sure if it's really a counterexample, though. Does 3-Lisp claim that you can only interact with values by calling their methods, or something like that? For example, can you impersonate a cons cell?
There has been several Lisp dialects (3-Lisp and T project) based on infinite tower of interpreters. You can build a language where the point where the rubber of abstraction hits the road of reality is nowhere to be found.
