I live in a country where that slippery slope has been completed a few hundred years ago already; we have no old forest in the Netherlands, any forest we do have has been replanted and is usually publicly accessible and managed, ideally as a protected national park like de Hoge Veluwe (https://www.hogeveluwe.nl/en) which nowadays has wolves again (that migrated in from the direction of Germany)
US is 237 times larger than Netherlands. Netherlands also is 17.5M people. If US had the same population density, there would have to be over 4B people in the US.
And that is not including the area that Netherlands had to recover from the sea.
The general public has proven time and time again that they are incapable of respecting natural areas and following rules and accepted etiquette. We should not be spending money increasing access so the worst of the worst can ruin even more of the country's special places.
Its certainly the case that installing bolted rappel anchors can encourage more people to climb a route, but the presence/absence of bolted belay/rappel anchors is far less of a deterrent than the presence/absence of protection bolts (which is why few people are disputing the the long-standing ban on power drills in wilderness areas). Put another way, if you claim the only reason you've never attempt Rocky Mountain National Park's Casual Route is because you're not good at building anchors, then I would argue you'll have a dangerously hard time with the rest of the route too.
The right balance between access and preservation is a difficult one to strike, but I would argue that land managers should err on the side of enabling more access because it allows them to proactively direct traffic into areas that are more durable to greater traffic, and stave-off potentially preventable accidents like this one:

and this one: https://gripped.com/201304/rock-climber-dies-on-rappel-from-... (I've rappelled from the anchor that killed Heung, and the fact that it must be somewhere where tat can be wrapped/tied is, I think, a major factor in why it was so exposed to rockfall. Its also a cautionary tale about backing up and testing tat anchors before fully committing to them, a lesson that people don't seem to learn even in the absence of "fixed" anchors. Consider this accident as well: https://americanalpineclub.org/news/2023/6/7/the-prescriptio...)
There is a certain tension in that the nature of the experience of wilderness areas is necessarily exclusionary. For example wheeled and mechanical transportation is excluded with limited exemptions for the disabled, the current limitation is that wheelchair users MUST use chairs that are 'Suitable for indoor pedestrian use'. Indoor use chairs are notoriously shit on natural surfaces, but should we allow ATVs? Probably not. Should we allow handcycles so disabled people can go through mud? I think so, but purists think otherwise.
The best wilderness I've ever experienced is the Mojave Wilderness. A place the size of Rhode Island, with 4 roads, a handful of trails, and a visitor's center. Otherwise, it's basically untouched desert. Absolutely gorgeous.
IMO, there's one fundamental difference between a park and wilderness: a park is a curated experience, and as such is a product of, and a part of, human civilization. That intrinsically means you are at the whims of others, perhaps benevolently so in the case of National Parks, but manipulated nonetheless. Wilderness means freedom from that omnipresent force of human intention, because the wilderness has no intention for you: it is ambivalent to your presence. The desert won't help you survive, but it's also not going to try and kill you or rob you, either. That's freedom you can't find on a trail overlooking a tangle of roads.
Except in the busiest parts of the park, you don’t have to stay on trail, and there are hundreds of square miles of roadless areas of the park. It is 3x the size of rhode island. There is no “tangle” of roads as there are only 5 roads that enter it. Like I said: once you are 1/2 a mile from the few roads in the park, you have it to yourself, and it is not a forgiving environment.
Yellowstone offers the full spectrum of experiences from stroller friendly boardwalks to multi day wilderness through hiking routes that never cross another trail, let alone come close to roads.
There's room enough for both man-made parks and wilderness areas, but to keep wilderness wild we need to stop making them human-accessible. I mean the whole point of wilderness is that it's not accessible, helpful, friendly, easy. The wild is harsh, dangerous, remote, unkempt, challenging, but also beautiful, tranquil, awe-inspiring, soul-filling.
