Eliminating some taxes does not necessarily equate to reducing 'national taxation' levels.
In this case a bunch of special taxes that don't collect much revenue, cost too much to enforce relative to revenue collected, etc.
The bigger taxes (by revenue collected) like income and VAT aren't being dropped. Revenues from those might even increase because these other taxes probably reduce taxable economic activities with those, like the Export Tax.
"Under the proposed reforms, the number of national taxes will drop from 167 to fewer than 20, focusing primarily on value-added tax (VAT) and income tax. The plan also includes the elimination of export taxes, which Milei described as detrimental to Argentina's agricultural sector—a critical component of the country’s economy."

This guy is great, he's like a combo of Ron Paul but with Trump's fiestyness. And he's got Austin Powers Mod haircut.
