The article says farmers are storing their soybeans because of inflation. I doubt you would want to store soybeans in a silo for more than a year. You have to also recoup the costs of planting and I’m sure you can’t just replant the soybeans you have without having a problem with the conglomerate you bought the seeds from.
It is plain that the farmers are planning on holding out for a higher price down the road, not forever, although you could take them to a cannery and have them canned to last 20 years if you wanted to hoard them for your own personal use.
If you buy heirloom open pollinated seeds, you don’t have to worry about some conglomerate’s rules. The companies who sell open pollinated seeds won’t bother you, and in fact sometimes will even give you info on how to save your seeds to use again.
It all depends on whether you want to do what it takes to be independent, or be beholden to the gonglomerate.
