Great example! Easy to understand, and clearly away from any "conspiratorial" answer.

Just to tack onto it...

> Once you get started again, you crank up capacity to 110/day - it takes you 900 days - almost 2.5 years - to recover that original shutdown deficit, without accounting for any of the increased demand for your product.

This is best-case scenario. Likely is that a few % of your workforce will have been out sick with covid (or even passed away), and a few % of your workforce may have quit to care for family, or quit for better pay elsewhere, etc. So your "work extra hard to hit 110/day" is more likely "work extra hard to stay at 100% or even 90%". Especially limiting if you need to buy parts for your output that may be delayed due to others who are behind.
