Something along this line: Google increases the entire value of the whole internet by a lot, but you also benefit more by investing in it in the early day.
In the normal case of one innovation in the free market, there is a punctuated moment of growth followed by a plateau. The owners of the innovation get the biggest share of the rewards, but after the plateau the benefits become more distributed. They would need to keep innovating if they want to gain further.
In the case of AGI, there is no plateau after the initial acceleration. With recursive self improvement, there is just an exponential explosion of growth. Unless this event was initiated such that distributed rewards were specifically intended to occur, the feedback loop would prevent external pressures from incentivizing any kind of distribution of rewards.
