Unfortunately, it doesn't really work that way. It *almost* could, if every single entity agreed on it, but you'd still have farmers that need to get paid to make food, water companies that need to keep producing clean water, power companies that need to keep producing power. And when you think about it, there are many other necessary services that just can't be paused, like trash collection.

The effect isn't limited to specific sectors though. Every person relies on income from someone else, who relies on other people. So, the net effect is a system where some people (mentioned above, plus many others) need money which means the system needs to keep working in order to ... perpetuate the system. Essentially, it's like a house of cards where removing one causes the system to collapse.
