The state will take over the entire supply chain to ensure that it transacts in a currency that it controls, crypto or otherwise.

Without that, the shared physical and legal infrastructure that supply chain depends on would cease to exist, and with it the supply chain.

Individuals, or the small communes that act financially as individuals in the crypto based trading system would have to trade in the simplest raw materials and finished products would be all have to be made hyper locally. Otherwise what entity would secure the transit of high value finished goods from supplier to customer?

I understand that it's a vision of the future that many people relish for its "freedom" from the state (but not so much from the local tribe). But universal crypto based transactions are not a drop in replacement for what we have now that keeps everything else the same. They come with their own radically different future-primitive vision for the world.
