There is no but-for world in which you can separate the investment spending and overall economic growth aspects of the tax cut from the revenues and tell me that we would have taken in more tax revenue if only we hadn't cut taxes.

It's like the idiot lady who asked Bill Gates to imagine how rich he would have been if he had never sold any shares of Microsoft. If he hadn't sold any shares of Microsoft there wouldn't be a Microsoft as we know it. The "lost revenue" from tax cuts is the same. It is a figment of the imagination that exists only in a world that doesn't exist and never could, because the economic growth that generated the revenue is in part the result of the tax cut you are imagining never happened.
