I think you missed out on a few things and underestimated the complexity of the law and of accounting (beyond simple bookkeeping/process execution)... plastic pipes don't replace plumbers who are still needed to install them. You still need HVAC techs to do the install/replacement, and shipping 100 pounds of copper overseas, is insanely expensive.
I noticed you didn't put electricians in your list.
There's no plastic pipe solution you can buy to replace the need for a human to hook up your 120 / 240 volt circuits, troubleshoot wiring issues, and repair / install service panels.
