He is pushing an agenda. The organization that employs him and publishes the article is Koch-funded. (They're a member of the State Policy Network). http://www.greenpeace.org/usa/global-warming/climate-deniers/front-groups/foundation-for-economic-education-fee/ http://www.greenpeace.org/usa/global-warming/climate-deniers... They push the standard Koch agenda- impugn government so that the rich can pay lower taxes, and so corporations don't have to spend money to protect the climate. So this article is standard fare for this type of organization. As you say it's too bad the article overlooks how much better toilets are today. The article also misses how fuel efficiency regulations failed, and how a high gas tax in 1970 would have been a great way to reduce American petroleum dependence. That example of regulatory failure doesn't often get mentioned by Koch allied organizations, however, because they never want to say taxes are good -- the very wealthy really want to avoid paying tax.
