If you actually want to only do business in cash, you're already going to have a very bad time. 95% of jobs (99.9% of decent paying or professional or large company jobs) won't pay you in cash. The same for any sort of loan or finance (who can you borrow money from without leaving an electronic trail?). What sort of landlord or mortgage company will accept actual cash? Can you pay the tax man with it (probably but good luck). The truth is, you're already in a cashless society for the vast majority of your income and expenses.
