There was a very good reason for it back when physical money was more necessary. Now, there’s essentially no purpose except crime. Almost all purchases are payed cashless. If you really want to use cash, almost no transactions are prohibitive just using $20s or $50s. Maybe buying a car or house would be tough, and I’m sure someone does that with cash, but that’d just be the cost of choosing to use cash.
