In my view, we hold public lands in stewardship, that is, while we are to enjoy them today, we are responsible for preserving those lands for future generations. As a polity, we have assigned the role of determining what that means to our government, and we know exactly what those entrusted with preserving those lands think that entails. I see that as a floor, not a ceiling, by which I mean that I see the Leave No Trace expectations laid out in the link above to be the minimum I should be asking of myself when I go into the Whites.
We have also determined that we have other places for leaving our waste, such as outhouses, sewer systems, and landfills.
So with all due respect, I think the dichotomy Tim has laid out is not the correct one. The correct one is that we have been asked not to leave anything in our parks, from a dropped peanut or a tossed apple core, to toilet paper, to the cap of a beer bottle, and the only question is whether we will respect that request or not.
I hope we all do!
Why? Because when we toss the apple core or leave the toilet paper on the ground, we are introducing something to the system that isn't native to it.
