If we want to talk about practice versus theory, you brought up the specified gas emitters, which is a carbon price on large emitters where the funds are not revenue neutral. They went to a government-sponsored fund, very similar in design to the Turning the Corner plan that was proposed during your time in government, one of the many carbon pricing systems proposed during that time. That's something that does not offset other taxes. It does not reduce the size of government. In fact, it puts a quasi-governmental organization in the role of allocating funding to whichever winners it chooses.
