Another could be someone lets you use their land for free, so you use the land to grow a unique breed of flowers. Later you find out that person that owns the land is selling honey from bees that visit those flowers (solely or in some combination with other flower patches). This honey revenue depends on your proper upkeep of your flowers.

Okay, fine, its the cost for using their land.

But THEN, you find out that your flowers (or, again, the combination) are so unique, that person begins making millions of dollars in revenue off the honey.

As the primary producer of the income, I'd feel a bit shafted if I didn't get some of type of reciprocation.

Doubly so if that person accidentally let a malicious entity on the land who then stole my unique breed of flower and then started selling/reproducing it.
