I am curious how this contrasts with the increasing freedom of movement -- people are increasingly able to pick and choose which city to live in.<p>One of the greatest &#x27;anchors&#x27; holding an individual or a family to a city is cost, so what happens when that cost is reduced to the bare minimum? Would we see the migration to urban centers <i>accelerate</i> (eg: Chicago holding &gt;50% of Illinois&#x27; population rather than the current 20%)?<p>Would we see a return to informal alliances like the <i>Hanseatic League</i>[1] as cities increasingly view their Federal overlords as inadequate or obstinate?<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Hanseatic_League" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Hanseatic_League</a>
