The answer to that is yes... Everyone should be able to do a little bit of plumbing.

However you don't need to a plumber every time you use the toilet so that's a bad example.

The concern is scale, Someone cooks your food every time you eat. One person can only cook for a limited number of humans. It only takes a dozen people to actively provide water to every house in a city.
