Not trying to hate here but this product is better in the offline world, such use case don't need to exists on the blockchain, there many projects that introduced something like you have here and after raising some funds they just disappear or dumped their tokens, you don't need to create any tokens for this
I think I have not heard any project related to agriculture, soil and many that succeeding, so you are right. Many of such projects have not succeeded, either because they didn't realize enough money which is also because investors don't believe in the reality of it and would not invest. Most of the project are exit scam.
Interesting opinion. Maybe the general trust level id very low.
