Yeah no, not at all. It's a real problem when Mt Everest is so overcrowded that people are dying. The problem the author points out is that as the population and middle class grows it inevitably leads to more travel, but many of the wonders of the world don't have the infrastructure to support the massive influx of people. The truly wealthy have the means to avoid the crowds, they can fly private, stay in exclusive resorts, rent private yachts. This is a very modern and new problem of overpopulation meeting an increasing amount of free time and wealth.
