That would be antieconomic. Culturing a truffe means buying a tree that cames "pre-configured" in a lab and letting it grow. This young sapling would cost, lets say, 80$. Thus they would be burying 1000$ for a lottery ticket with a small chance of turning it into a new 80$ tree. Very bad idea. Anybody can buy a pre-seeded tree online. Eating the truffe instead is advertisement and creating a net of future exigent customers. For chefs is also an opportunity to verify that you have exactly the right stuff. There are other types of truffe that grow in Corylus and have a much lower market value.
