I started a hand sanitizer company that was based around stockpiled inventory and pitching an uninterruptable supply of sanitizer to government entities. They hated the idea and when the company was forced to pivot to different types of sanitizer products we had to destroy a quarter of the value of the company in un-sellable sanitizer.
The ability to pivot and move is too valuable to get rid of I think shrinking supply lines so more things are produced locally is more likely though that increases the chance of a local event causing more problems.
