Zillions of nodes created when exporting to A. Illustrator

I love how easy it is to use the brush tool, but when I export to ai, thousands of node points are created. I can simplify in ai, but it seems so unnecessary when a totally manageable number of nodes are created in Vectornator. What am I doing wrong?

Please pardon my ugly jointery and such, I haven’t edited the paths yet.

My client will be laser etching the final design using ai, so it has to load correctly in ai, even though I am drawing it in Vectornator.
