The essence of NIMBYism is wanting to make the value of your own property increase, not by adding any value, but by restricting others from competing with you. That's a net harmful behavior so I think it's fair to describe it as "an evil force to be mocked and dismissed". Kind of like if Google lobbied the government to ban search engines which weren't Google Search. People would see that as evil too.
