As someone mentioned in another thread...The WHO Digital Passport will keep you in your 15-minute city.
They(?) are going to implement this idea somewhere in the UK soon (Oxford?) IIRC. You will be ‘allowed’ out of your 15 minute area several times per year. WTAF? No suburban or urban living. Think multiple high rise apartment buildings.
One being considered in the UK will have a rule that you can only leave your designated zone 100 times a year. After that you get fined and I bet if you kept doing it or left and didn’t come back, finances frozen like a Canadian trucker.
