Can’t say for sure, as I don’t have direct experience in the paper industry, but I seem to recall that paper producers don’t log pristine forests, rather they farm trees for the desired characteristics. Therefore if there were no toilet paper, there would be no need for the trees used to produce it, and the (private) land would be put to other uses not likely involving trees.
The big paper producers grow thousands of acres of select pines for their use. The will plant 3 acres for every 1 acre of harvest. This insures that they will always have raw product for the future. Virgin forests are much harder to harvest from because of the undergrowth and the tree spacing. The paper manufacturers make toilet paper, paper towels and printer paper and without logs on their yard, they will go out of business.
