I totally agree that it is not perfect and it doesn't scale well. If that weren't the case then all the farmers that grow tree crops would be rich. I think the point of my article was to point out that there are natural processes that are amazingly productive.
Also while in hind sight buying and holding BTC would be an effort free and super profitable investment, past returns on man made investments are no guarantee of future returns. While the returns from trees are pretty reliable as long as you do your part to choose the right varieties and location and take care of the soil.
Oh I agree, only Nature is truly abundant, all human activities that claim to be abundant are either virtual (non-existent outside the realm of machines) or based on natural processes!
In an interview with Ben Falk (or it could have been in his book, not sure) he talks about the sentiment of Bill Mollison that an yield of a natural system is unlimited. The idea being that Nature , if fostered and not destroyed, will always yield more than we can make use of. So from that thought stems the principle that it's better to have half an acre of properly managed, regenerative and fully productive system than 10 acres of badly managed one.
