I feel like by dealing with a part of the problem you first have an understanding of the system as a whole so that you can isolate the root cause aka the part of the problem it's not route in terms of the base or foundation of a problem it's root in terms of dealing with the actual causal issue
Policing and laws often treat symptoms and not the "root" cause. Financial laws addressing fraud don't try and solve the underlying human greed yet they are valuable in trying to the protect victims of fraud.
Saying we can only solve fraud by addressing the underlying socitial reasons driving people to commit fraud would be crazy. The symptoms can be dealt with it can and make a difference while also working on other causal factors.
It doesn't have to deal directly with the "causal issue". It just has to reduce the negative effect.
