Financial statements can be sent electronically. We are literally creating huge volumes of paper, spending a ton of money and creating a ton of CO2 and other industrial waste, just to send a bit of information that could’ve been an email that most people just throw away without reading anyway.
Buses and roads are used by millions to get to work/school. Police are protecting you even if you never call them (countries without credible police are extremely dangerous; police have an extremely powerful deterrent effect against organized crime). Even if you’ve never driven or used a bus you’ve definitely eaten food that has travelled on a road multiple times before reaching you (unless you live on a commune out in the country in which case you probably shouldn’t be paying taxes for all that stuff).
Anyway the point wasn’t even that there shouldn’t be a postal service, just that we don’t need daily delivery. If we eliminated non-addressed mail and made all financial statements electronic then the postal workers would be driving empty vans around town every day. We could easily switch to weekly delivery without impacting service much at all.
