I’ve seen wheelbarrows used for that kind of thing. It’s not like you could drive into the house anyways. The distances to the road portrayed in the image look quite reasonable. If one has no roads it becomes an issue if there is no replacement. For personal transit there are plenty of alternatives in cities. Pedestrian roads that can be opened to vehicles as exceptions also seem like a good compromise. I don’t know where you would ride a bike if there’s no road either. Some cities I’ve been to have bike lanes wide enough to fit cars too.
