Finished the second last story: "Utere Nihil Non Extra Quiritationem Suis: Novella" by John Scalzi

This world has city states and autonomous regions, and then it has the wilds, outside of these self-sustaining spots. This is the only story looking at life inside these cities, which have a wealthy, better off vibe. Pretty cute in some respects, looks at working life, weird biotech and the best part is the relationship between the main character and his friend, a biohacked pig he named lunch.
