maybe this will force factories to change their process. with manufacturing getting cheaper, smaller batches become affordable. at the extreme we can now print books on demand, and improved 3D printing allows one-off items in many more areas. that's the trend we need to push. to get away from wasteful mass production.

Push how? Through regulation? Unclear how else you’d achieve this if it is still worse economically. Buyers don’t want to pay more either.
