Sure you would not need to do work for a customer or employer in order to make money if you did not have to pay property tax
But if you do not pay property tax who will fund the roads
And if the roads are not funded then how can you drive to another location to make money to pay for property tax
It is not like people invented flying machines that do not use roads
@BowsacNoodle
You can get small packages delivered by flying drones.
& it would be cheaper to pick people up by helicopter in case of a medical emergency and put out fires by a fleet of drones with water then to fund the entire system of roads
Roads are also bad for the environment
I like sidewalks but all that road space could be used for gardening so each person has their own garden to grow food to reduce reliance on the employment system
Distributism
Each family has means of production
