Other countries also have different population numbers. To take a random example, why would e.g. Uruguay (population 3.5M) buy as much from the US (population 100x) as the US is able to buy from them?
Besides, if the trade volume is what determines the tariff, why would any country want to have a trade surplus with the US? The best solution for other countries is to artificially limit their exports, or find more reliable trading partners.

Because the U.S. can buy from Uruguay only as much as 3.5 million people in that country can produce.
On the face of it that sounds reasonable, but then you look at say China with a 35x population over Canada yet Canadians don't just buy as much from China as vice-versa, they buy CAD$65 billion more. So I don't think the argument that larger countries necessarily have a deficit against their smaller trading partners holds water.
I do agree that this madness will only encourage other countries to conduct their trade elsewhere.
