Tariffs would make it harder for people to distinguish between price increase for the sake of profit and price increases from supply chain inflation. This makes it easier for large businesses to charge more and consolidate out the smaller players in an industry. It’s a short/medium term solution to the tendency of the rate of profit to fall. This is just crocodile tears from an entirely irrelevant intermediary capitalist, presumably to get some kind of cushy small-business tariff exemption or tax credit.
Also the Tax Foundation is a very right wing (libertarian?) lobbying group who should not be taken seriously for any opinions on any topics.

I looked up their WY SOS filing, and yeah this is almost definitely an S-Corp. (S for small). That status is already an protectionist measure: it bypasses the corporate tax level so long as xyz conditions are met. One of those conditions is having no foreign ownership. (‘nonresident alien’). I don’t even really mean this as a hypocrisy gotcha, the whole article’s vibe is propaganda by juxtaposing two forms of corporatist protectionism and setting the pre-justification for raising prices.
Also the focus on racist cowboy garbage and electoralism disguises how important this stuff can be. Like I have no idea what the price of 10-gallon hats is because it doesn’t matter in the way that food or electricity or rent does. The target audience is libs who will say “haha maga ppl won’t be able to buy their 10-gallon hats anymore if trump wins but they’re so brainwashed that they support him anyway haha” It’s just ridiculously condescending.
