What you haven't considered is in what current state is the 30-60 million dollars investors sent this company (as fawtsc points out, far less was apparently spent on trees and maintenance), and the increasing value of the large tracts of Costa Rican real estate owned by it (far more than those planted for investors). The resulting net worth may very well approach being equal to the outstanding purchase prices of investors. Costa Rican real estate is not illiquid and it will be increasingly valuable despite the recent worldwide dip.
Just waiting 10-30 or more years while being limited to following the TATF website and its 'what's new' page, offers a very low probability of resulting in any return at all.
I don't stop discussing this scheme just because we no longer owns any trees. Harm was, and continues to be done.
If there was a scintilla of direct and informative communication to investors we might believe differently. But there is not.
