> Nobody is cheering for inflation to get worse, they are celebrating it being held down to 2.7% after higher inflation a few years ago.

Trump is actively fighting the federal reserve to drop the interest rate to 0%. Members of his team regularly do interviews where they say "it's going to get worse before it gets better". Inflation is being held down despite this administration's best efforts.

> The U.S. is a net exporter of oil and food and self-sufficent for majority of its mineral needs as well.

And has been for a while. But the current conservative rhetoric is specifically about bringing manufacturing jobs back.

> There is no need for U.S. to crash its currency to incentivize domestic production, it can just impose tariffs on imports to do so.

I don't think autarky is this administration's only stated goal. They specifically see an export-led economy as being more important or even "legitimate" and are pushing for other countries to import our goods. Devaluing currency is a strong way to incentivize exports and China's currency manipulations were the key to their rise as a manufacturing power.
