People are willing to pay more to Apple than to Foxconn for an iPhone simply because intellectual property law prevents Foxconn from realistically selling the iPhone at a lower price. When one decides the iPhone is the device for them, they have little choice but to buy it from Apple at whatever price Apple has decided to charge. If there were no such IP encumberments, Foxconn would sell an identical device for a lower price and people would quickly forget who Apple even is.

Farmers approach landowners with better offers all the time with no qualms about paying top dollar to get it. Being a farmer myself, I can tell you first hand that competition for land if fierce. Sometimes the approaching farmer is taken up on the offer, sometimes not. But I see no real indication of pent up demand that isn't being satisfied because people cannot figure out who the landowners are. There is literally a land registry, if all else fails. But rural communities are small. You already know who owns what, and conversely who farms what.

It remains: Where does Tillable fit?
