1. Mathematically, we don't need to distinguish between technosphere
and biosphere, this can be one big matrix. In practical terms, our
biosphere will be a different set of names; or, they will be flows for
which there is no associated producing activity.
2. We don't need the concept of a reference flow to make a
technosphere matrix, and there isn't anything special about positive
numbers of the diagonal. Production amounts can be randomly ordered,
and in any case everything produced is positive, everything consumed
is negative, regardless of whether it is a reference product,
co-product, or whatever. The notion of reference product is helpful
for humans trying to understand the reason a particular dataset was
modelled, but irrelevant for the computer doing the math.
