Whenever I see something like this I'm conflicted. We shouldn't need to sue for things like this, it shouldn't ever be allowed to happen in the first place. Obviously do it if you can prove it, I have nothing wrong with the person suing, but it just shouldn't need to happen in the first place.
That's something nearly all professional economists would agree on as well. Its literally Econ 101. Generally speaking, if a government taxes something, there ends up being less of it. Taxes are a disincentive.
