You want sewage? You sign up for sewage. Everybody who does, has a week assigned where they must do the necessary maintainance for that utility.

So I'm supposed to learn everything about sewer maintinence before this week, or are we throwing untrained people at critical infrastructure simply because they want to use it? And what then if I also want food, transportation, a computer, cat food, smokeables, drinkables, shelter, etc? Do I have to become an expert in all of those things too and work in those to get food, shelter, etc? Have to churn butter for a week if I want access to the butter store, and make bread for a week to get access to the bread lines, then I can make toast?

Personally I'd prefer if there was some way to make what I make or do what I do, exchange those items or services for some thing with an agreed upon value, which I can in turn take to the store and trade for bread and butter.
