The "point" of the tariffs is that Trump likes tariffs. There's nothing more to it than that.

Why cut off your thinking there? I can think of many reasons why he would like tariffs. Two off the bat:

- Allows claiming various benefits like onshoring production, or reduced taxes. This is for the voters.

- Allows threatening other countries' industries with tariffs unless they invest in his friends' enterprises. This is for him.
