It's 107,361,000 acres. I'm not sure that qualifies mathematically as "way more," but it's still only five percent of all the land in our country. And you've just betrayed your willingness to reduce even that, so your arguments about all those roads being closed, the mileage of which you have been unable to substantiate, are irrelevant anyway. You're simply annoyed by the very concept of places you can't drive to, and you have, consciously or unconsciously, admitted that by your statements.
Fortunately, a majority of the American people disagrees with you, in contradiction to your "tiny, tiny, TINY percentage" accusation:
Nearly nine in ten Americans believe that protecting public land as part of the National Wilderness Preservation System is important, according to a new Zogby International poll of 1039 likely voters across the country. These voters view as “very important” (57 percent) or “somewhat important” (30 percent) the protection of publicly owned land as wilderness, leaving it just as it is. The support cuts across political parties, regions, age groups, and ethnic and religious backgrounds. Twelve percent said it was not important to protect the nation’s wilderness.
