Because largely, nothing of our capital goods are being destroyed. Most humans are still alive, and we can employ the manpower to run the equipment to ensure we are fed if it comes to that.

A fragile global system in which during a pandemic, people are still fed and clothed? It's actually a testament to the modern economy that the pandemic hasn't resulted in immediate shortages for basic sundry goods. The few shortages we are seeing are for highly specialized medical equipment (N95 masks are not simple cloth covers).

There's certainly weakness in our system.

Basically, preparing for a pandemic look like waste to us. It's equipment and goods that aren't be used to satisfy the needs of people.

We are fragile because we rather buy cheap mask from oversea rather than making sure that our mask production industries have enough what it needs to produce masks in the quantities we need. And we are fragile because pandemics preps have no advocates when it come to government downsizing. And because we don't have a pandemic as deadly COVID-19, we don't war games to find weak sots and spend even more money to fix our weakness.

And all weakness that are fixed are never going to matter until we hit an especially deadly pandemic.

It's like a race car versus a normal car. A normal car, people likes reliability. They don't care about getting from point A to point B fast as possible. They don't care about the extra mass that keep them alive impacting the fuel economy some amount. While the ideal race car is the car that break apart at the finishing line, with engineering margins shaved until the edge of failure.
