What stories like this show us is how little freedom you have once you build your life around modern convenience. When you use a dishwasher to clean your dishes, you are forced to buy whatever commercially available products are out there — even if there are no government regulations at all.
If you have the skills to design and build your own dishwasher, then you don’t have to care much about these stupid regulations.
We have a dishwasher but we never use it, frankly it doesn’t do a very good job, so we just do them by hand.
