Hi, I think this man just wants to get more attention by making some noise.
Geostatistics is the great contribution of geoscientists outside the mainstream of statistics to the science. I also ever met a reviewer. The guy never agree that parameters should estimated from correlated data. At the beginning of the development of kriging, I guess Professor G. Matheron must met lots of challenges. As Professor Journel pointed out, geostatistics does not pursue recognition of mainstream mathematics, it pursues recognition from practioners. It is great because it is useful. If just checking geostatistics purely from the view of conventional mathematics, there are lots of places to attack. But our understanding of geostatistics also should not stop on the conventional geostatistics. Geostatistics is also evolving. The recent proposed multi-point geostatistics is quite innovative. In addition, Markov chains are also evolving toward a new non-kriging geostatistics.
