> all with incentive and opportunity to lie to some other members along the chain, but not to their immediate neighbors

And how does blockchain prevent them from lying?

> you need to sign up and authenticate literally all the farm organizations in Europe, and all the competing grocers and transport companies. They all need to sign that they trust the third party service to be a fair and neutral record keeper

Instead they all need to sign up onto the blockchain and lie directly on the blockchain

> Each tomato can have its own blockchain with attested entries from each fertilization, spray, and transporter, all added and attested at the point where lying is hard

Fertilizer put on the record that tomatos are fertilized.

Sprayer put on the blockchain that tomatos were sprayed.

Transporter put on the record that tomatos were transported.

You arrive at the shop to find rotten potatoes instead.

How did blockchain help?

Also note that in this current world that is so horrible according to you you arrive at a shop to find tomatos that have passed all inspections and have been delivered to you. What eaxctly does blockchain intend to solve?
