I can see why you might ask this, but the book very much focused on the idea that a piece of land much preserve space for a parking space. It might sound innocuous but it is the source of many issues within cities, a contributor to housing inaffordability, why so many buildings in the US are surrounded by miles of parking, why some of the lots in your city are derelict, etc.
The book very much addresses why mandated parking minimums even in suburban residential lots are also bad (specially the mandated minimum less so the carpark itself), I highly recommend the book mentioned above.
Here's the preface of the book http://shoup.bol.ucla.edu/PrefaceHighCostFreeParking.pdf
There's also a good audiobook.
Now, instead of letting car owners pay for the public space they use (street parking), you are forcing anyone without a car to waste their own private space, in case somebody wants to park there.
The subtle difference is between American parking minimums imposed on property owners - “you must reserve space on your private property for this many cars whether you own them or not” vs Japanese parking requirements imposed on car owners - “you must reserve space on some private property for your car if you want to own it”
