No, it’s not a tautology, it’s a pragmatic principle.
A tautology is a statement that’s true by definition and doesn’t add new meaning (e.g., “A circle is round”).
An ontological tautology would be:
A system that supports the kind of life one thinks is worthwhile supports the kind of life one thinks is worthwhile.




Which of the systems allows for you to pursue your ideal system - an activity which you would probably add to your definition of a worthwhile life?
