So does food from the supermarket. That’s why we give poor people money. We should, IMHO, give them even more. Either way, with that money, they get on the bus.
Half of the world’s population walk miles for food and water. That’s certainly not a big ask on a bicycle. I commute six miles each way to work on a bike, every day. For millennia, humans roamed hundreds of miles on foot hunting for game. Yet you’re arguing someone today can’t cycle a few miles?? Lordy.
Delivery is often cheaper than the time and commute, so I’m not sure what you’re arguing there. Amazon offers free delivery, and you can buy every staple you need.
