Many think that using money for everything everything will decimate pubic services – with UBI everyone will have the money to take an Uber for example. And go private on health care. UBS seems better so it keeps public goods in the public realm.
Yuo need to imagine that each UBI account has a public service credit card and some of the UBI is actually earmarked as credits for public services – busses, maybe food, water, electricity bills etc. This is a kind of rationing and gives everyone enough for their need.
The principle is the same- The game illustrate where the money comes from and where it goes. We could do a UBS version it would look very similar to the UBI one.
