Well, the example wasn't particularly rigorous, just meant to shed some light on the subject. Even if it is valid, the assumption (that all processes are reducible to fundamental particles) is pretty clearly false.

Moreover, though, composition isn't always a fallacy (unlike ad hominem, say). In this case there is sufficient justification to make the inference. Of course, the simplistic statement "atoms don't have free will, so you don't have free will" is fallacious, but I only wanted to make sure my meaningwas understood.
