Hmm. doesn't look that much feasible mate. Maybe you guys should just opt-out of being a DAO and created in advance a possible way for users to interact with this "digital earth"; that way people will have a better idea as to what to expect when they would own a piece of those lands. One way I could think of using this "digital lands" is to use virtual reality technology; businesses, small shops, and even service providers could buy and own a digital land and put up their digital store/shops on it, then their costumers can access it through VR. But then again, that not the direction you guys have chosen; a bit unfortunate.
BTW, some tips, present the real people who are the backbone of this project, you know, transparency. That's the very key part of being a DAO.
