in that analogy the fence (Knots’ stricter policies) doesn’t eliminate garbage but it does throttle how much gets in.

Core’s approach (garbage cans) = assumes people will cooperate if you give them the tools (filters, incentives).

Knots’ approach (ban + fence) = assumes bad actors will still try, but the barrier significantly limits the volume of garbage they can bring in.

So while some trash might still get tossed over, the fence reduces the load compared to leaving the park wide open. It’s less about perfection and more about controlling scale.
