What is a baseless trope? It doesn’t sound like you’re using “trope” correctly.

There’s no theoretical upper limit to many concepts, rendering that comment irrelevant, but anarchism historically has a practical upper limit on group size and proximity. You can’t indefinitely grow your population without taking logistics and territory into account, and the lack of centralized resource management necessitates territorial expansion.

It sounds like maybe you have a question. You can ask that question.
