This seems like an attempt to avoid the argument rather than engage with it, because creating an imaginary world which we currently don't live in has nothing to do with the reality we're currently dealing with. The reality being that one informs the other. I know people that would agree in regular situations that we need some enforcement of immigration law. But this is not a regular situation, and when you have an agency tasked with 'enforcing' immigration law who is not enforcing the law at all and in fact violating the law, people question why said immigration laws and agency exists in the first place.
