Nice fantasy. Nobody will pay for the first, the second will be a complete illusion with the current state of public transport (and how you want to get people with 30+ km commute one way to bike, even electric, will remain an unsolved riddle). The only thing with the third is, you are right, it will change, I.e. it will kill off in-city retail completely.
Goods:
Rail, tram, cargo bikes interconnected at re-implemented logistic centres.
Workers:
Public transport, (electric) bicycles
Customers:
Retail will change, but cities will not lose their function of overspecialisation.
