I agree. By all means anyone tell me to shut up...

Yes - exactly! And in nature there are, I contend, no _tokens_ of such
trust. In particular, no organism A can give a token to B, who can then
give the same token on to C, who can then 'spend' it.

In nature, trust always works by direct recognition, memory and
reciprocity. (That, incidentally, is the reason why we are uniquely
good at distinguishing people's faces. There is a PhD thesis to be
written there on why more-or-less all banknotes and coins feature faces...)

That money can't survive in a world where anyone can make anything they
want (including money...).
