Or classical capitalism, because 99 ton of wheat plus one ton of sand is one ton of wheat cheaper than 100 tons of wheat. Sand is heavy and cheap.

I just happen to have bought some sand recently, and it isn't that cheap. Especially not the type of sand that you'd feel comfortable mixing into food.
Where I am, a ton of sand aggregate using in construction is ~$100 per ton. The better sand used in gardens, the brown sand (it's used to repel water so you don't over-water crops) is more than than.
Considering the wheat/ton spot price is $160 per ton at the moment, I don't think the actual prices would be too different.
