Not actually advocating good-will, just a kind of symbiosis in the form of low-time preference with common hope of good long term outcomes.
Any short term 'good will' would actually just be more like bets on longer term good outcomes.
It's the inverse of what we see in places with low hope (low confidence in the future), where hit-and-run is a better bet than stay-and-grow.
Re: zaps - i think of them as baby steps towards the idea of paying-for-value, they're not a silver bullet, but they hopefully lay the experiential foundation for #value4value commerce.
