Don’t forget the huge energy savings (heating/cooling, transportation, infrastructure) by having denser housing. It isn’t just a measurement of “I can see trees,” but all the daily human activities that have a reduced environmental impact in denser development. It’s counter-intuitive, but rural areas that are “nearer to nature” are often worse for the environment.
There is probably a break-even point, I don’t think everyone living in skyscrapers is ecologically ideal and I wouldn’t want to live there anyway. But medium-density development with multi-unit (shared wall) buildings allows huge energy costs, while also making public transit more viable and providing a tax base that actually pays for its own infrastructure.
For the record, while the Supreme Court justices have refused to hold themselves to the same standards as lower court judges, a U.S. District Court judge like Cannon is indeed bound by the Code of Conduct for United States Judges and the policies of the Judicial Conference, which do require disclosure of such gifts and trips.
