Yeah, I mean, would the private interest have NPR style pledge drives, essentially holding the pristine nature of the parks hostage? What happens when pledges don't exceed what can be harvested in resources? Does this really mean that the pristine parks aren't truly valued? Or are there different forms of value? I'd say it's likely the latter, and that the libertarian lean is some how flawed if the degradation of nature by the free market is supposed proof that nature isn't actually valued, or that it is valued less than Tupperware and Snuggies.
