You’re conflating tariffs with duty taxes collected on imports, and that’s a big part of why this conversation gets muddled.
I don’t support broad tariffs either — I’d love a world of free trade. But duty taxes aren't the same thing. They're not necessarily protectionist; they exist to fund the enforcement of customs and import regulations. If we agree that there are things we should regulate at the border, plants, animals, counterfeit goods, etc. then you need a mechanism to fund that enforcement. Duty taxes are that mechanism.
De minimis creates a loophole where foreign companies can flood the market with small direct-to-consumer shipments, bypassing both duties and most scrutiny. A U.S. importer pays duties and follows import regs. Temu doesn’t. That’s not about "harm reduction", it's about uneven enforcement and subsidized noncompliance.
I'm all for optimizing enforcement of small package imports and making compliance easier for individuals and small businesses. But we can’t pretend that zero enforcement cost is viable at scale, or that eliminating duties across the board is somehow neutral in its effects.
If you're arguing for removing all import duties and funding border enforcement from general taxes, fine but say that. Otherwise, it feels like folks just want all the upside of globalization with none of the costs or responsibilities.
