Sympathize with all who hike in highly regulated areas. But they are a great argument for hiking in Wilderness Areas that are under a totally different department of the federal government, and have very little of the overly bureaucratic behavior of the National Parks. The Wilderness areas have regulations, but they are far less intrusive, and are online and posted at trailheads.
One could argue that the Parks need their bureaucracy, because they are so crowded. A good argument. But it is also a good argument for hiking in the Wilderness Areas, where I’ve often gone for weeks without seeing a soul.
I like to hike with dogs for many reasons, including that bears shy away from them. But Rocky (RMNP) is vigilant about keeping dogs out, even on boundary trails needed for through passage on the CDT. So on one occasion, without dogs and before I had discovered the route from Rawah Wilderness south in to the Never Summer Wilderness Trail, I had to detour through Rocky, and found it so overused, it has no wilderness quality whatsoever. The route was often on gravel roads, and went through a place called Lulu City, that looked like it had been trammeled by a million rhinos. Finally, just beelined out to the Park road, and hitchhiked to the first trail outside the Park boundary.
Suggest that backpackers will find more rewarding experiences in the Wilderness Areas, and far less bureaucracy to contend with. If you know how to camp safe, then less supervision is a blessing, not a problem. And there is just as abundant scenery in the Wilderness Areas, more actually IMO, if only because of the serene atmosphere of the mountains.
Agree that for areas outside the continental US, it is a different story. But I’ve been backpacking in Wilderness Areas in the lower 48 for years, and would still never be able to tour all the most beautiful areas if I lived to be a hundred. Also, my expenses are not much more than when hiking at home. Drive, not fly. Much of the food is already prepared and packed in a portable cooler.  Stay in small friendly motels and cabins wherever possible. It is a great way to learn about places and a country I never would have known existed, and make great new friendships.
