What are the disincentives to infinite city sprawl in Civ6?
In fact ICS seems like the best strategy to cope with the hugely annoying 'whack-a-mole' barbarian situation.
If every single patch of the world is not covered and locked down, enormous numbers of barbarians will continuously spawn from all directions, disrupting international trade etc.
And since new cities don't cause unhappiness elsewhere (Civ5), require gold to support (Civ4) or suffer from low production caused by corruption (Civ3), then there isn't really any reason not to plop down a city in every possible piece of land you can grab a hold on.
