Interesting how you point out mankind needs nature but in the same breath talk about all the infrastructure.
I have an off the grid property with no roads to it (legal easements but nothing improved) yet my nature is marred by a giant substation powering all the civilized parts where people build infrastructure. I can literally hear when the power demand increases from a half a mile away.
The irony is you think we demand the govt for something. The govt doesn't produce anything, except waste.
If we want a road out here we get a tractor and make one.
Here is an example of people producing infrastructure with no govt waste.
