This ties in with your second point. There are uncountably many ways to accomplish the goal of making a chair or writing a program. And if you are a carpenter working on a one-off matched dining set for a fickle client, the problem might not be as clear as even many software tasks are. Your skill and experience is highly likely to play into the eventual form and structure of the finished work. The customer might not know where you hid the dovetail joints or dominoes, but they can absolutely notice the grain continuity and lack of obvious engineered joinery evident in a factory piece.
If you don't care, then fine! You can focus on the other things that bring you joy. But I hope you can appreciate that some of us want to experience solving these problems with a bicycle for the mind instead of a Waymo.
