I said "but people don't do that because there are better alternatives".
I also said "with monograms" for example, i.e. there are irl handmade sweaters made today because people don't necessarily want a factory product.
I pointed it out because it illustrates a hint of the principles of "comparative advantage" which concepts are useful for analyzing more than international trade, analysis the majority of people aren't familiar with.
Comparative advantage falls flat on its face in the circumstances being described, though. It’s based on an assumption of opportunity cost that no longer holds true.
