The thing is that we don't have any (data) infrastructure in place to do
this. The only one we do have in place is tracking money only... according
to the paradigm that this would reflect a summary of the "worth". Which it
obviously doesn't...

I think something like an accumulative "resources used" data set with every
sold item would make sense. Not necessarily terribly precise, but a lot
better than what we have now.
