It's a Public park
A public park is meant to be used. If individuals are causing damage to the park they should be individually held responsible for the damage.
If I started a kite company near a park and people bought my kites by the thousands and went to fly them in the nearest park, I am not responsible for the damage those people cause. They are individuals, individually participating in the same activity. I didn't tell them to go to that park. That's where they chose to go as there was open space and wind.
When a flower bed gets trampled by a kite flyer or a AR player it doesn't matter which they were doing, the person trampling the flower bed is responsible for the damage. If the city or state tried to hold me responsible for the damage they would get laughed out of court. Same for the AR company.
The AR company should work with the parks system to create an experience that works for everyone. Randomly created objects should be shunted to the nearest footpath or parking area. So players can enjoy the park and not cause damage. A system should be developed where an organization can send a set of areas and where the game content can be safely moved to to preserve safety and security. It could be an online map where you outline an area, draw on the safe zones and in 15 minutes the game is updated.
