I don’t know, the concept just makes sense to me intuitively. There are enough weird effects in systems and math when things are at zero that I just can’t tell what would happen. Example, in queueing theory when input rate is equal to output rate under reasonable randomness you get large backlogs. When everything drains at just a few percent over zero it just seems like a better system. The US also had a civil war during that period. And then repeated brutal boom and bust cycles until Breton Woods.
