I don't think you really know whether the tariffs are going to work or not. It's not hare-brained, as you say because it has two purposes: 1) To attempt to bring manufacturing back home and 2) To raise capital in order to pay down the debt.
If you look at the debt clock, 2 is working. As for 1, it's a long-term project and you're being too impatient. Also, you are subject to the mass media hand-wringing propaganda that states that everything Trump does is automatically terrible because Trump. It's childish and nonsensical to think that way, however. We need people who think outside of the box and it's not like Trump came up with "tariffs" by himself without the input of smart economist thinkers.
The point is, you lack the big picture.
On point #1, if the US ends up in a shooting war with China (because China is expansionist) it would be very bad for us if we are unable to manufacture critical supplies, particularly semiconductors, whose manufacture is concentrated in Taiwan, a brittle and untenable situation for the entire western world.
Be a crybaby and downvote me now, or listen and learn, your choice. I agree with the rest of what you said, btw--the whole article is just bs.
