The logistics issue is that we have commercial and retail supply chains that are Apples & Oranges level different in terms of getting end consumers what they need.
For instance:
1) Commercial Offices - why is toilet paper disappearing especially in big cities? It's not the production side that's failing. It's that a huge amount of toilet paper is bought and distributed by commercial contract stockers. The supply chain has NOT adjusted to get commercially stocked toilet paper to retail centers. And making it worse commercial distributors are FORBIDDEN to sell to retail in many cases! So now you're dealing with a supply chain + beurocratic issue. There are Mt. Everest sized stocks of commercial TP sitting in warehouses all over America.
2) Commercial Restaurants - These establishments fed the MAJORITY of office workers in major cities up until 3 weeks ago. Commercial restaurant supply chains are reeling - they have stock sitting on shelves and are trying to figure out how to get it into the retail supply chain with similar beurocratic and logistics issues.
There is not a food / grocery shortage and there is unlikely to be a food / grocery shortage in the USA.
But it is going to take some time to sort out how to adjust to this new normal.
And inevitably as soon as we figure it out the pendulum will swing the other way :)
