ELI5: What would happen if nobody in the world bought anything for a day? How about a week? A month?

Likely not much.  All that would happen is everyone would rush out the following day and buy 2 days worth of stuff.  The same would apply to a week or a month.  

There would be some problems at the busienss side of things.  Having the right levels of inventory and staff would be dificult for the buying day.  The non shopping day would be a large cost savings if the retailers knew it was going to happen in advance (no need to open and staff the store) and a cost sink if they were caught by surprise.

Overall, not much would go wrong.  People are going to buy what they are going to buy.  It would just wait until tomorrow.
