I have another theory.
What if Shatoshi gave up.. in a way that he doesnt care ?

He saw that kicking the hornet's nest will bring trouble .

He also saw that the vitality and passion of cypherpunks was transforming into
something more akin to  goldrush mentality and that the community they were
propably seeing  was an illusion.

I mean he stopped in an non orderly way. And there are cypherpunks who have
expressed likewise , turning their back to the 'experiment'. Bitcoin is just
a laye they say.. lets move on and let CSW play. Who cares?

Well .. maybe a father should care where he leaves his child.
(so i bet that definately not a woman)

And in that way a trait of their character surfaced that is little childish.

Programmers know how many negative traits have been attributed to RMS and Linus.
Two persons who in my programmer soul bear bigger weight that some Cypherpunks.
And although they are not perfect thay definately didnt turn their back.
