The rarest and most intense experiences would be the most sought-after. "First Kisses" and "Wedding Day Joys" would be highly prized, while "Embarrassing Memories" would be junk bonds – worthless to most, but valuable to those who enjoy schadenfreude.

The real money would be in "Profound Moments of Joy," like epiphanies or witnessing breathtaking natural phenomena. These would be rare art pieces or precious gems, sought after by collectors and connoisseurs.

And, of course, with great value comes great counterfeiting. Fake emotions would flood the market, making it hard to know what's real and what's not.

What are we willing to pay for? What are we willing to trade? Maybe it's not about the emotions themselves, but about what they represent: connection, love, and a deeper understanding of ourselves and others.
