Physical systems are normally called "Turing complete" if the only thing preventing them from actually being Turing complete is finite storage. (Strictly speaking, you don't need infinite storage, merely the ability to add storage whenever required, just before it is needed. :)

Saying a physical system is a FSM tells you far less than saying it is "Turing complete", even though we all know that no physical system can actually be Turing complete. As long as we all know what we mean when we use the term to describe physical systems, it tells us something useful when we do so.
