Idk, I'd put it in the same category as doing a crossword puzzle, building a LEGO set, doing some DIY task around the house, etc. A nice diversion that's not entirely creative but stimulating enough, and at the end you have something functional/interesting or at least satisfaction that a particular problem has been solved. It won't change the world or your life or make a million bucks, but not everything has to.
Very much agreed.
There is a difference between learning woodworking as a fun hobby that would allow you to make a chair for yourself vs. doing it in hopes of turning it into a profitable business venture that would make an impact on the world.
By the grandparent comment logic, there is no point in doing anything, unless it can somehow lead you to making an outsized impact on the world. Thus essentially declaring most hobby pursuits (that are done mostly just for the sake of fun and learning) as wasteful.
The analogy would be more like just buying a premade wood chair and assembling it vs doing any actual woodworking.
