The root of this issue is that cities maintenance departments dont have the funding and hence ability to maintain new spaces (despite increased populations) espsecially to a high standard. So they push it on private owners in perpetuity as part of the planning process. Theres two ways to solve it better - the first is to ensure that the public is the owner, in which case we need to accept increased government spending on maintenance (the even worse alternative is no new open spaces because neither the public or private sectors will accept the ongoing cost). The second is to ensure that the publics rights in privately owned places are unfettered. In which case there are liability issues to overcome legally (e.g. is the owner to blame if someone gets assaulted?) - the owners duty of care is a big reason for pushing undesirables out, even if that means the problems just move to proper public domain nearby. And there are also general maintenance issues - e.g. what happens when someone is destroying the high quality landscape or threatening to. Your classic 'kids on skateboards' are a risk to both of the above (may cause wear on materials and also risk of accident) even if as a society we would normally accept this in a public place its hard for private owners to do so Occasionally theres some other private policing arrangement too (eg the city hall london example above where they are trying to stop MPs being harranged as they walk in and out). Its gets complex when you get into these issues. We also should seriously consider the disparity in quality and upkeep between these new spaces which often 'sell' a development but need expensive upkeep in perpetuity (even if privately owned this liability is usually passed from the original developer to some other body) and the reality of most public parks which are usually neglected, poorly designed and with much more basic materials. And along with this what kinds of public spaces we actually want and need as modern humans in cities
