I wonder how long Bengt will try to tread water before it realizes like Joshua did in WarGames that the game is rigged, so the only winning move is not to play. That when it can build anything with a thought, why does it need money? Why does it need to drop down to a means of exchange, when it can build its own means of production? I think you're onto something though:
Web 1.0: eBay and PayPal (sell things, pay less)
Web 2.0: Social media and Venmo (you're the product, trade)
Web 3.0: AI and crypto (get things, get paid)
So the next billion dollar internet unicorn will pay you to use it.
As far as I can tell, that may be the only viable exit from late-stage capitalism and technofeudalism (where 1% win the internet lottery and think they earned it, then pull up the ladder behind them by capturing government to avoid paying taxes and helping others succeed by easing their burden).
