tracking of food produce 'from farm to plate'

at the moment food is just categorised as grades of how 'wonky' veg is.. where straight veg goes to supermarkets and wonky veg goes to a factory to be chopped up into soups, stews, mixed veg meals and then tinned or frozen
by making food more trackable things like a 2 week 'sell by date' can then become more manageable that when food is not sold by day 10 of 14. its then repackaged as chopped up meals to then be tinned or frozen. thus not ending up in landfill

also allowing for more meals to be packaged lowering the costs aswell. plus could be handed off as donations to foodbanks and soup kitchens. thus also legally not holding the supermarket liable for any risk of harm from what they percieve is threats of litigation for passing on out of date goods.
....
ys i know the digital/physical divide can be cheated. such as opening a crate of fresh vegs, emptying it and putting in old veg but not replacing the crates batch identifier can be done easily. but then it can become a crime/civil fine of more than the crates value if caught doing so to make it not worth doing it
....
land ownership disputes and costs of trading land can be minimised too by a simple crypto transaction instead of requiring lawyers to draw up deed paper transfer contracts, also having less requirement of agencies to store and validate such information where as 'estate agents' could themselves be the nodes which then do all the processes at cheap rates of say $1 cost. thus then lowering their cost and thus commissions but still charging a fair value for the hard work of advertising, doing walk through tours(open days)
..
even things like a list of precise to the metre longitudes and latitudes to define each square metre can be batched together as a hash to represent a 'plot' of land. and where only the plot needs to be registered thus it wouldnt require 510billion entries for each square metre but 1billion entries for an example of plots 510 square metres
(225gb of data to cover the entire land ownership of the planet) making it managable to do using standard computers and not requiring servers in government central agencies

these precice square metre identifiers can also make distribution logistics and even postal, parcel and taxi services more manageable by knowing which 'zone'/patch/area is covered by which courier/driver

imagine parcel couriers who are given only $£10 an hour but made to do 10 deliveries an hour. $£1 a dropoff for 6 minutes. yet taxi drivers, same labour same fuel charge more per 6 minutes.
so imagine the taxi/courier service merging where it be person or parcel. the fee is the same

imagine it like each driver stays in thier zone and passes passengers/parcels to diffrent drivers at each zone border

then you'll see less vehicles crossing paths which can be a waste of fuel and time. such as not needing to travel across a town or city with only 6 minutes time allowance as goods/parcels/people are 'swapped' mid journey making it faster to get things done by not having to go out of zone
