Great ideas, but there is one major flaw in insourcing ag with these products.
How many young folks want to spend their life farming? Drum roll?
I see this all the time living in red and rural areas where there is farming and agriculture, they simply don't.
A great example was a farmer I was eating dinner with a a bar in Indiana a decade plus ago stated this.
Al, you know the last time I had a young person work for me was in the early 1990s? If I do get a few they can't handle the work and they fall apart or leave. It isn't about pay either. I offered $20 hour flat and straight cash per hour to do this work, still the same. The only folks I have a chance of getting and maybe keeping are folks from jail, but then you have to deal with drug issues and them not showing up either.
This was early to mid 2000s.
The American society have essentially through neglect and poor attitudes have spit on farming and farmers, and yet pride themselves on their knowledge of food. Well, folks will not get to experience what shortages are, and this is not something that "just happened" it is a 20-30 year span of issues.
Now, the West Coast through the laws they implemented for social and moral good (no qualms their state their rules) have literally just crimped their entire supply of meats, dairy and other animal based products. So sit back and watch what happens over the next 12 months.
Purdue did studies of the chilling effect to the food supply when California lost 2/3 of it's supply due to law enforcement. If we take pork, California consumes 16% of the pork in the USA. After the laws go in place they will only create 4% of the supply. Think about that.
As for the other types of farming, they are regulating water supplies aggressively, which means that farmers will stop producing those good too. Take the shortage of trucking and limits put on trucks due to climate change, do you see an issue?
I have called this out personally since the mid 2000s, and received shrugs. So folks are free to believe what they want, but I can tell the impact is real and the costs will go radically up.
Point of reference, on my horse farm we used to spend $4.99 per 50lb bag of feed, now we pay $24.99k .... The time frame? 15 years ... you do the percentage of growth, and realize IMO folks should get ready for food price increases in that level for the next 15 years.
