I think you are somehow correct here, sometimes people can misbehave a lot in their best interest in getting extra funds from people they are trying to help or working with. There are some locals especially the chairmen in many of these local areas that will want to compromise the process just to make more money from the team. That means LandDAO must make sure that they are dealing with the right set of people in these local regions so the process of acquiring these lands in large quantities will not be jeopardized.
Do you mean somehow what might be the reason why you still have some atom of doubt? I know LandDao has a team of expert that makes research on the lands before bringing it up to the team to make the necessary arrangement to acquire the land. However, it will be better if the locals are government recognized. That is they are working with individuals under a regulated company that is recognized by the government of the country. For example, instead of random locals it should be real estate companies even if it might cost more. I don't know but it depends.
