Maybe I should rephrase my question (although the apparent misunderstanding has raised some good points).

Is it legal no have zero warpoints and zero system shields in my empire? It seems to me that this should be fine.

The reason I'm pressing the question is that I'd like to open a warp point to an empty system, ignite a star, and build a ring world. In the meantime, I'd like to close the warp point to my main cluster of systems. So long as I don't build a system shield in the lone system, and so long as my main cluster is accessable by other players, this should be legal, right? No system would be unreachable.

As I understand it, a "turteled" system is one that another player's ship can't ultimately access using either an existing trail of warp points originating in a non-turteled system or a warp opener, and the "no turteling rule" is that no system may be "turteled".
