I loved this, but just wanted to muse on how unlikely an economy based on tech that assigns numeric value to sentimental trinkets would be. 'Cause.. if all your money is tied up in stupid worthless shit, you'd expect gifts from friends and family constantly just to maintain a lifestyle. Your work wouldn't matter as much as being close with folks so that crap would have meaning. But then if you're used to giving things away constantly, what's around long enough to truly accrue emotional value? Hoarders would be the only billionaires in that society.'
ETA: Now, if that translated to all people having to produce art that's deeply meaningful to trade for food, we might have the makings of a beautiful society.
