I'm much more talking about things that have value only because people think they have value. That's mimetic value. These things are valuable because the meme of them being valuable has infected society.
Like money, or art, or education (except in narrow practical fields) or entertainment or a notional (but rarely practical) ownership claim on a company, or intellectual property,
None of those things would have any value at all if people didn't think of them as valuable, or treat them as valuable, or respect them.
Notably, a farm does not fall into this category. It is a physical asset that produces other physical assets; that's utility value, not mimetic value. You can eat its output for food or burn it for energy.
The more meta stuff is about how even physical and utility value assets are often partially acquired based on mimetic elements. So people pay more for a car that makes them feel like an international spy than they do for a car that gets them from A to B, so the meme of feeling like an international spy has increased the value of the simple physical asset.
