It is OK to categorize HA’s role as a commercial organization when it struggle with developers for a parking space, for a children’s playground, or just a piece of land, since this is what the developers have promised to fulfill in their advertisements. Homeowners’ movements here could be regarded as the “consumers movement”.
How is it different from the kind of movements like protesting against the meg-lev, or against a high-voltage wire? These issues go beyond the interest of particular neighborhoods. The homeowners are only one of the actors that could be influenced by the projects.
“The state” intervenes the consumers movement less and less today, since the market of the property management and real estate begins to be regularized.
In protests against the meg-lev or high-voltage wire, the homeowners are savvy in “disintegrate” the state. They insist that they are against certain departments of the government, not the whole regime, and they hope to rely on some higher authorities to check the powerful actors so that their rights could be protected. In those issues, it is really hard to explain what the “state intervention” means.
In some way, the logic in both issues is exactly the same. No “collective actions” endangering the stability of “harmonious society”. But in the former case, the state needs to regularize the market. (If you want to take the real estate developers to the court, fine. If you want to dismiss a property management company, fine.) In the latter case… well… where is the boundary?
