Some of us can't. I can sleep in a tent any time of year (although I'll pass if it's over 90° at night), but my girlfriend needs a CPAP and has back problems that prevent her from sleeping on the ground. We both love nature and have visited dozens of parks, but for health reasons we can't really hike more than a couple miles a day. We still enjoy the parts we can see near the roads and visitor centers. Every time we visit a new part of the country, parks are the first thing I look for. Both of us spent our childhoods camping, but in her case her parents were too poor to take her anywhere too far from Oklahoma, and my family mostly just visited the southwest. Neither of us have seen Yellowstone or California's coastal redwoods or Yosemite or Crater Lake or Glacier National Park, and those are all on our bucket list.
