I never met anyone who went backcountry camping and upon arrival to the campsite was delighted and overwhelmed by joy seeing dozens of other tents at the site.
You are the first one.
This is the whole point of outdoors: to escape people, city, and other day to day nonsense.
I know what you are saying. The idea is that if we don't tell anyone about the good hiking spots and we don't do anything to develop the trails then we can keep them to a small community and they will always be pristine.
The flipside is that if no one cares about hiking then no one will complain when access is gated off, recreational areas are clearcut and parks are turned into mines.
I firmly believe that the best thing we can do is to have more people exploring the outdoors.
