If that's true, it should be fairly simple (not easy...) to protect it: lots more people, with lots more money, are invested in keeping most/every tree standing than those needing or wanting to extract logs and minerals, meaning there's definitely a Coasian bargain to be had.

Seems to me that the conservation side faces a massive collective action / free rider problem (classical public goods theory)

They build a high-end, comfortable tree house with WiFi and running water, realizing that a few people visiting means the exclusivity and uniqueness can generate a lot of money for very little ecosystem disruption. He did so explicitly to help people see the divinity of the insane forest they're in, Rosolie being the foremost apostle of the "mythical church of the Amazon" (p. 61). He ends up efficiently raising money for his organization, finding a way to sell ecosystem services to wealthy patrons who made their living in the filthy, destructive global economy.

Probably not scalable to the extent that it would make a meaningful dent in counteracting the economic incentives of logging and ecosystem destruction... Right?
