Yes, of course it's impossible to literally leave zero trace, but with education and the intent to respect nature, it's possible to radically reduce ones impact to the point where no one should feel guilty about enjoying the natural environment. In many areas (such as delicate alpine areas) that's managed through permitting and restrictions on the numbers of people, though of course it still requires those permitted people to follow best practices and attempt to minimize their impact.
