The only difference lies in the infrastructure. Most people live in villages with their families. No distance from family members for the sake of education, job, or anything. Everybody fulfills his/her needs from home. Sounds great! Right? The condition is the same in one aspect for both our present world and the past world: cities have much more population density than villages. Job, travel, education institutes, medical centers, markets, everything is in cities. Those who are able, prefer to stay in the cities. Now, is it possible to reach scenario 1? If we look at the current world trend, we can see how everything is turning online: businesses becoming online, government works becoming online (passport, national identity card issuing, etc.), shopping becoming online.
