Sounds like this person was really smart to begin with. High-level societal awareness caused them to choose the private route, and focus on releasing something for the greater good.
I wouldn't be surprised if this person never even took a single bitcoin for themselves, other than the ones used for code testing purposes. That would create another avenue for people to come after them if it became public that they hoarded some of the Bitcoin for themselves.
This. Maybe, Satoshi saw where it was going, knew it had wings, didn’t want to be the elephant’s plaything in some senate hearing, and bowed out. Sometimes people make things because it’s the right thing to do. Other times people make things because they are experimenting and seeing what sticks. This was a case of both. The right idea, at the right time, without hubris, and without someone to blame or throw in court if the experiment fails.
Satoshi could have chosen a 0 BTC subsidy in the blocks he mined. Or he could have burned all the BTC he mined. But he chose to do neither, leaving himself as the biggest BTC owner ever.
Other coins have been designed in a way where the founders can only obtain coins by mining them in very small quantities or buying them on the open market (mostly by fixing the block subsidy forever).
