Distributing differential value (could be better phrased)
The option to make exchanges that increase my total value, incentivizes me to use my comparative advantage to produce new things that will be low value to me, but high value to others, so I can trade them. This increases the total value in the economy by both creating new value and distributing it in a more beneficial manner.
I would put it like this:
Comparative advantage
Incentive to produce
