In fact once you concede the economy is a giant machine the point is proven. All machines that are manufactured have problems according to random and chaotic failures. For example parts such as hard drives have a mean time before failure and overall parts like these are managed according to probability.

Other parts tend to fail catastrophically under load. For example metal fatigue, crumpling, collapsing etc. These can't be assessed with probabilty because the failure depends on getting to that point where suddenly a catastrophic buckling, ripping, etc occurs. This happens in any machine, and they are manufactured to balance out these two forces for maximum efficiency.

So since the economy is a giant machine using people as parts there are the same two forces. One is an average failure rate of employees for example doing something wrong, and getting fired then hiring someone else.

The other is catastrophic failure of parts of the economy by too much stress. Workers can be hurt by workplace safety standards being too lax and creating accidents that can catastrophically hurt people and infrastructure. People who lose their jobs can have a catastrophic loss of income that ruins their whole financial situation, while others have enough of a buffer financially to avoid this.

Like any part of a machine it is better to design it to avoid catastrophic failure, or to design it so individual parts are not overstressed. It's the same with people in the economy machine.

Ayn Rand touched on this in Atlas Shrugged where Dagny Taggart complained about bridge building being ruined by bureaucrats. Regulations at the time were needed because engineers didn't understand chaos very well, so a bridge could fail if not strong enough. So they used to build it multiple times stronger all over to be safe to avoid that catastrophic failure they couldn't mathematically work out.

So she was complaining about these rules from people who didn't know how a bridge failed but wanted to make sure it didn't. In many ways the economic machine was the same in those days, where catastrophic unemployment, inflation, recessions, etc occured and people only had vague ideas on how to stop them. These were resisted on the grounds they were socialistic and unscientific but they did work to some degree.

Nowadays these are better understood mathematically in the economic machine.
