Cosmos and Mars, Sun whatever else was there long before us an will be still there long after us. From cosmic point of view humanity does not matter much.
From that 1000ft view humans and whatever we built is natural and not different than colony of ants. We are just sand grains that will be crushed when next big asteroid comes by.
Having pristine planet like Mars has no value besides human point of view "I want". Let alone planets are not pristine they are bombarded with space trash like asteroids all the time :)
Why do we use such anthropocentric view? It makes any difference if there is parachute on Mars? Pollution? Well we defined pollution because it is something we want to get rid of because it makes us sick. There is much more bad things for humans in space than you can count.
A pristine planet has value beyond 'I want this' IMO - it is an opportunity to perform experiments in an almost perfectly isolated test tube.
As a human, I also find it beautiful. As you say though, this is an anthropocentric view.

They are the only way to protect your work if you are unsigned (think struggling artists).
