Even to this day, all that undeveloped farmland is dirt cheap compared to the hive life, and yet people vote with their feet and their money for the hive. For a substantial proportion of them, the first step is to exchange the countryside life specifically for this informal/improvised condition of dwelling, just to be close to the hive.

Mass urbanization into megapolies is 200 years old at best. With very few exceptions in older eras that didn’t house a big portion of humans in given eras.
I imagine in the future only the very rich will choose to live in some cities, the very poor will mostly have no choice and have to live there and large swathes of the middle class will love to get out into the country/small villages if their jobs allow it.
Same applies to urban living.
