[contingencies]

If we had some kind of software solution to track externalized costs, that would be a huge step towards reducing it.

Agreed. Supply chain in general is actually a substantial area requiring innovation (see shipageddon/chipageddon/every sales or purchasing department ever). I generalised some thoughts about an actor-transaction-oriented protocol model with features such as risk modeling, arbitrary assets (eg. physical trade) and settlement paths, arbitrary precision, fee/tax/discounts and redundant and multi-hop paths over here: https://raw.githubusercontent.com/globalcitizen/ifex-protoco... - since then I've moved in to manufacturing and it absolutely would be a godsend. Happy to help someone else pick up a similar line of development.
