All these cities are very different from NYC. To be clear, I'm not saying preserve the status quo. I just don't think the changes the cities you listed made have any chance to work in NYC. Most notably, all of these cities existed way before NYC and we're built with limitations of medieval technology. All the changes you mention are just rollbacks to last working state. NYC is a new city built with comparatively godlike tech applied without restraint. The NYC-style solution "I guess I'll just commute by helicopter, no problem putting another skyscraper right here" was incomprehensible to the rich people who built the European cities - they had to go a little further away if they wanted their quiet comfortable life.
