I share the Ron Swanson view on government
("as little as possible"), with a few key exceptions. One of those is the natural environment. It's actually a truly "conservative" cause and it baffles me that the GOP doesn't seem on board with that.
We haven't yet found a good way to give common goods real costs. It feels like that could be a blockchain application (though before government adopts something like that... look at the mess that is carbon credits).
Anyway, some of these pictures of the US in the 70s are incredible. I am very thankful to the environmental movement of the 80s.
