Honestly I get the sense that you're not even reading these links. They do not substantiate the argument that you're making.

I have at least skimmed every one of the links you've shared (except the Atlanta BizJournal since I don't have the nationwide subscription) and none of them say what you're suggesting they do.

I agree there's a problem here. I agree that these risks kill many projects before they are birthed. I do not agree they come anywhere close to the costs of land, material, and especially labor for any actual construction project. Nothing you have posted even attempts to argue that, AFAICT.
