You seem to have interpreted the analogy as meaning "you might run out of turtles" instead of something like: "stacks of turtles aren't stable without stable beneath them, no matter how many turtles you use."

Space them out. I meant that infinite stack of turtles can be stable, of finite height, and for practical purposes, cut off after few layers without noticeable impact on stability.
