The way I hope to see it is that all the different features are apps that you can either enable or disable and then the AR platform (e.g. the OS on your headset) just mixes them all together. So for example there could be an app for placing sculptures anywhere and it becomes a matter of that apps policy. If you don't like an app that lets you place sculptures anywhere just don't install it and use the one that ties in with property register. And so on.
This would also reduce the BK Ads in MCDs example to what we have today. It's not illegal to show BK Ads on peoples phones while they are in MCDs.
