This is fully what I expect it to be. Peaceable by keeping out unwanted people (poor people). I don't think we have it in us as Americans to truly build a proper egalitarian society. We don't really know what that looks like. As a substitute we use whitewashing and just shuffle around the unfortunates out of sight and pretend it's been fixed. If this "city" doesn't have low income housing and community social services you'll know it for what it is.

They can automate away an increasing number of low-wage jobs, but they'll still want people to clean their offices and serve overpriced coffee.

Maybe they'll have service entrances and hidden car parks where they let the low-wage workers in and out. Conceal the fact that eco-utopia still relies on a whole lot of road traffic bringing people and goods in and out. Really, it'll be an 'eco-utopia theme park'.
