Having actually travelled there, a lot of authors assumptions are invalid in a way that reveals our (euro-american) biases. There are no roads, but people travel by plane (both jets, our guide made a joke that there are two kinds of airlines in Papua, ones that crash into mountains and into the sea, or prop on grassy landing strips, you can look up videos from visiting remote villages, those pilots are super skilled) and on the coast - by boat. Smartphones, solar panels, FC Barcelona t-shirts and catholic church made their way into the mountains and jungle before any other sort of infrastructure, and so did the tourists and fake attractions: fake cannibals, fake legends and fake customs (even BBC fell for some). Demand gives birth to supply. One super interesting thing the author does not mention is that Papua is the last stand for betel nut chewing: you can try it if you're into light psychedelics. I can also shill my video essay here of anybody is interested in listening to pseudophilosophical/journey journal ramblings in heavy accent: https://youtu.be/0cCoZguizdg?is=o-5urE4E2GTolaDv
