"whether your words line up with your scent, whether you are worthy for them to take the intimate, vulnerable step of “pledging their troth” and placing their lives and futures in your hand."

I think investigating this can lead us to understand how loyalty and honor are assessed. There is very little of this occuring, but we want to build relationships and environments in which this can be constructed. We have more portability now because we can prove honor more reliably with all the tracking data (I think social scores, initiated by the people, will make a big comeback) to know you keep your word. Things like prediction markets, smart contracts and reputation in high status communities will matter.

There must still be a physical component as well.
