> Closing loopholes is a problem and it just becomes a war of attrition with accountants and lawyers.
I think that's unfortunately true, but there must be a point of diminishing returns. Close enough loopholes (intentional loopholes or otherwise) and companies end up spending more money on tax lawyers than the value of the actual tax break. Even if some companies are able to use some loopholes, closing many of them still means more tax revenue for states. We don't need to get to a "perfect" state here.
