It is interesting for a targeted campaign like this administration's—which claims to be concerned with government waste and inefficiency—to cut employees for one of the only organizations that we know causes decreased revenues for the federal government when it receives cuts in funding [1].
Of course, it's not like they're implementing any sort of new policies to make sure productivity in the IRS remains the same. I'm not sure why we'd expect anything less at this point.
Insofar as you're tariff-ing everything that moves, the less you particularly care about internal revenue. The endgame is to eliminate the income tax entirely anyway, so why would one want the IRS at all?
Because it's all about libertarian, anarcho-capitalist, utopian ambitions like Curtis Yarvin where all government is "the problem" without evidence or admission of reality.
