pretty sensible isn't it, why complicate it with a third party, if you don't trust the buyers currency don't sell.....the reserve currency concept is heading towards its destiny as a barbarous relic......anonther failed human experiment (though only because the humanity kicked in).....
hmmm what we need is something
durable, divisible, convenient, that has value in itself, transportable, can't be used up, isn't a liability to any nation and has long history of being accepted as a store of value.
gee, if only we could find something like that to use as money the world may be able to return to progress, but where could we find such a thing?
