Mass manufacturing has replaced handcrafting in pretty much every field. Its not economically vibable to handcraft when mass produced alternatives exist.

Crochet is a craft that is not automated. You could probably build a crochet machine, but it would be incredibly complicated, expensive, and doing so would be slower than a human. Its not a viable craft to automate.

There's a reason you don't see crochet clothes in stores. It takes dozens if not hundreds of hours to make a crochet garment. No one would spend thousands to pay me to handcraft a shirt over several weeks when they can buy a mass produced shirt for a fraction of the price at a store.

Hand crafting is great, as a hobby, or an act of love. Its a terrible idea as a profession outside of very niche cases. Few can afford to spend 10-100 times more for something that is hand crafted when similar alternatives exist.
