Why not? We are able to design systems, and we are able to objectively recognize and understand emergent behaviors in arbitrary systems. Sure, we can't exhaustively find every emergent behavior, but we are not 100% blind to them, either. The only way to guarantee an emergent behavior continues is to preserve the structure of its system. That means the only strategy that can change emergent behaviors is a strategy that changes systems.
