Seems to me 'money' is a 'social construction' in the same way that 'race' is. Both are 'real,' sure, but the basis for that reality owes more to the rules we impose and our experience of living within those rules, and our choices to accept certain absurdities, rather than any description or other factor.

In a game of Roulette, the house 'exploits' how gamblers focus on the 18 Red and the 18 Black slots, ignoring those 1-3 'other' slots (usually green) which confer the advantage to the House. Gamblers tell themselves absurd stories to justify their bets, 'knowing' their stories are absurd, yet stubbornly clinging to them even so - enough to create risk and the possibility of a 'story' (particularly if Rick Blaine steps in to fix the game so as to rescue a refugee from exploitation).

My guess is that whatever we THINK is in an emoji, we should try to acknowledge that someone is probably exploiting the absurdity of our beliefs. Should the possibility anyone might attempt to claim identity through color choice lead us to look for 'green slots' that might be somewhat more subtly hidden than on a roulette wheel?
