The comment you're responding to was literally pointing at the actual magnitude of prices for scopes that are merely US-branded. And for the lower end models you're talking about, they're not even anywhere near "Made in the US from US components". Siglent or Rigol are not going to be setting up manufacturing in the US to avoid tariff rates on finished products, and they certainly aren't going to do it when the inputs would be subject to tariffs as well.

Your comments in this thread basically come across like you just read an economics 101 textbook and are now asking leading questions to continue your study. In reality, markets are computationally hard and path/structure dependent. Merely tweaking a few knobs to increase some incentive won't make something magically spring into existence. A lot of market "proponents" ironically miss this - if markets were not computationally hard, then centralized planning would also work!
