Enforcement being unjustly balanced in favor of the rich & powerful is a separate issue from whether there should be enforcement in the first place—"if we must do this, it should at least be fair, and if it's not going to be fair, it at least shouldn't be unfair in favor of the already-powerful" is a totally valid position to hold, while also believing, "however, ideally, we should just not do this in the first place".
