Well stated. I used to work for The Seed Savers Exchange, and we worked very hard to keep the pure, heirloom seed varieties in production. They have an extensive "Seed Vault" to protect many old varieties that are naturally resistent to many diseases.
But, that said, the Government maintains two or maybe three such vaults themselves. So...we'd be back to Square One if things all went to h#ll anyway. The Government could easily still be running the show, at least in food crop production, which may not be a totally bad thing until we can get back on our feet again.
But, I save garden seed from year to year, anyway, and can talk at length on the subject, should anyone be stupid enough to give me an opening, LOL! Not to be an alarmist freak or anything, but it makes sense genetically and fiscally to save seed from year to year (if you truly know what you're doing.) I keep a standard selection of seed (rotated, of course) in with my 'End of the World Disaster Kit.' ;)
And I also wanted to add...Remember that old song called "Wildwood Weed?" Jim Stafford?
"One day this feller from Washington come by
And he spied us and he turned white as a sheet
And he dug and he burned
And he burned and he dug
And he killed all our cute little weeds
Then he drove away
We just smiled and waved
Sittin' there on that sack of seeds..."
LOL!
