This took the "$400 million / hour of shipped goods are being delayed" figure and ran with it by multiplying it, claiming that's the total damage cost.
Now ask yourself: Let's say you're sending a parcel via UPS that contains an iphone, or simply $1000 worth of goods. At the last stopping point of the UPS truck, they get a flat tire before being able to deliver it. Your iphone delivery is unexpectedly delayed for a day.
How much damage has been caused? What if it's two days? Six days?
There's just a big fat "this isn't how it works" attached to this $58bn figure.
Edit: For context since parent comment was deleted, this refers to istheshipstillstuck.com's estimate of $58bn worth of damages being caused by the ship being stuck.
Also, consider that we're at the end of a financial quarter, and this could also account for missed targets for all manner of industry.
This is going to be bad for some individual businesses (imagine a small business buying a whole container of perishable goods), but systemically it's a blip. Delays are not destruction. Failure to make something is not the same as spending resources to make it only to have it destroyed.
Money shifted around to different winners, but very little damage occurred.
