Most people who are knitting do it purely for the experience of knitting. If you need clothes it's far more affordable to buy the cheap manufactured stuff. Some people certainly enjoy the creativity of expression and wish they could get to that easier - but most of those people have moved away from manual tasks like knitting and instead just draw or render their imagination. There's genuine value in making things by hand as the process allows us time to study our goal and shape our technique mid-approach. GP may legitimately like knitting more than making clothes.

I think you misunderstood my post. Now many people do knitting for the joy of knitting, but people used to knit to create clothing to wear or to sell. Of course, automated knitting machines have largely replaced hand knitting, and people now still do it. If you are very good at hand knitting, you might see if you can sell some work. However, if you want to make knitted clothing at scale, you would be better served taking a high-level approach to the actual design of the clothing and learning how to prompt the automated knitting machine to do so instead of optimizing for how you yourself would hand knit it.
