I don't agree with this entirely. To some extent it depends on what you mean by "world class".
I have done a bit of walking in the UK over the last 10 years. If you have ever walked or travelled in Britain, you would realise there is no wilderness in the sense we mean it. Every square inch of the land has been worked or forested or farmed for thousands of years. Yet there are literally dozens of marked and well-used multi-day walking tracks that could be called world class. Most of them cross farmland, which is possible because of the historical accident of certain routes having been public rights-of-way for thousands of years.
Two years ago, I did the Offa's Dyke Path, which follows the border between England and Wales. It took two weeks. We walked along roads, over farmland, through odd little parks, on river banks, through towns. The accommodation was usually some distance off the track, as much as several kilometres for some.
Then there are all the other National Trails, such as the Hadrian's Wall Path, the Pennine Way, South West Coast Path, etc.
http://www.nationaltrail.co.ukThere are also lots of unofficial paths, such as Wainwright's Coast-to-Coast, the Dales Way, and so on.
These walks are extremely popular, and bring regular income to shops, accommodation places (and pubs) and transport companies along the route.
None of them involve wilderness, but many have other attractions, such as historical monuments, great views, pubs for morning tea, lunch and afternoon tea, etc. They are doable by ordinary people who can carry only a daypack, and are very accessible to public transport.
What I would say is that the web site seeking suggestions lists a whole lot of day walks as examples. People do not come from the other side of the world to do an isolated daywalk, or even from a long distance in NSW or Australia.
In the UK, most of the walks are structured around the time periods people usually are available. Most people can only get a weekend or a whole week off work, so the walks tend to be two days, 7 days, or 14 days. If day walks are to be included, then there better be a bunch of them fairly close together to keep people busy for a weekend or a week.
New Zealand is a little different to Britain, in that there is more emphasis on carrying your own food, bedding, etc, but huts are provided to stay in, and campsites if you prefer and want to save a little money. Walks also tend to be around the 3-5 days mark, with some substantially longer (eg, Dusky). Daywalks do not feature highly in the walks available, and are certainly not why people travel all the way to New Zealand.
Local businesses also benefit from the walkers in NZ, in terms of food and drink suppliers, transport companies, and accommodation places near the start and finish. Some walks have commercial huts but they coexist with the independent walkers with no apparent problems. (We even have an example of this here, in the Six Foot Track.)
