I see what you mean and respect what you are saying, but what was the alternative during the periods of “selfishness”? At the time it was being done, it was probably not thought of as selfish, but as making your property conform to the expected standards of the day?
Maybe the definition of “selfish“ has evolved?
For example, most of us look at smoking as being very selfish today and people of yesteryear smoked at alarming percentages. They killed themselves (at great cost to society in insurance, forest fires, etc.) and harmed people around them. Decades of education and millions of people dying from smoking related illnesses later has the effect of reducing smoking. Now smoking is viewed as more selfish than back 50 years ago.
Has owning and maintaining a lawn become like smoking? Is having that beautiful lawn at the cost of adding harsh chemicals to the soil and pollution to the air from mowing become like smoking? Have education on the harmful effects of lawn chemicals and lawn mower air pollution begun to bring a change in what the societal norm for a “lawn” will be? Or is it the demise of the lawn altogether?
Is having someone telling us we cant have a sprawling beautiful lawn taking away ones freedom of using their land the way they want, or is taking that freedom away a method of creating a better society?
