I am quite amazed how many people here underestimate the dangers of a cashless society. You should know the Chinese social credit system. From the German Wikipedia:
"The Social Credit System is an online rating or "social scoring" system in the People's Republic of China. It represents an attempt at total control of the population by awarding "points" for desirable behavior (from the point of view of the ruling Chinese Communist Party) and withdrawing them for negative behavior. The system goes hand in hand with quasi-ubiquitous surveillance, the data from which feeds a large part of the points awarded. To this end, the social and political behaviour of private individuals, companies and other organizations (such as non-governmental organizations) is analysed to determine their "social reputation." Anyone who achieves a score level that is too low must expect restrictions in everyday life, such as access to social services or the search for a job or training."

Only a cashless system enables the government to cut every citizen from the goods he needs for life. Without money you're a 'Mister Nothing'. In Germany the bank accounts of critics of the government have been closed, and this even several times. For example of Boris Reitschuster, a well renowned journalist who even left Germany and lives in Montenegro for some time now.

A 15-minute city at first sounds positive, if you read that all activities and services (supermarket, bank, doctors, cafés and restaurants, leisure areas and so on) are within a range of a 15 minute walk. BUT: Do you remember the curfews during the Corona plandemic? With the concept of a 15 minute city it would be possible to prohibit leaving this radius. It would be possible to ban cars at all. Why own a car if you can reach all facilites within a 15 minute walk?
In fact 15-minute cities means battery caging for people.
And a word regarding the complete surveillance. In Germany we have the concept of "smart cities". Some years ago the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection published the "Smart City Charta"
There you read:
"Post-voting society
Since we know exactly what people do and want there is less need for elections, majority decisions or votes. Behavioral data can replace democracy as society's feedback system" (p. 43).
But after the publication was popular outrage especially on this and other proposals of the concept. Some time later the "Smart City Charta" was shortened and remarks as this one were cancelled.
