Do you know how to join copper pipes? The difference between PEX and PVC? The various pipe fittings and their benefits/costs/tradeoffs? Do you know how high a pipe can rise before you need to add additional pumping? I'm pretty sure you turn the faucet on, and expect drinkable water to come out, without thinking of what's going on between the source of the water and your sink. Yet, anyone, given the right motivation, can use and learn all those pieces and parts, and make use of them at whatever competency level they have. You can even make a soccer goal net with PVC. There is room (and need) in the world for all people to explore, geek out, and use these details. And the people who are passionate about these details, and the intermediate pieces should be cherished, because they are the ones that will understand and fix the intermediary pieces when they break. Sometimes, making money is not the goal.
