This is an excellent point. I've been looking into blockchain as used in supply chain integrity. Here is a company currently doing it: https://www.provenance.org/whitepaper I have been wondering about how this will circumvent the diminishing scope of regulations in the US food and textile industries, and how this will present much better provenance data for the principled consumer and how this might disrupt current interests of US corporations. This would be great for the consumer, but bad for the corporations' bottom line. I can see it somehow being legally derailed via what you just outlined since it could direct consumers to better options hurting the profits of corporations who paid hefty lobbying sums. I hope this won't be the case, because I like the use of blockchain to help with supply chain integrity. It is a path toward sustainability in an increasingly hostile-to-sustainability market.
