I personally feel that this is less of a logistics issue (given that one or more billionaires are involved in this entire project), and more of a, well, security issue, so to speak. Because as far as I can understand, plenty of Dark Hats are yet to be grabbed / arrested, and given that folks like the CIA / FBI etc. are involved in here, I'm assuming technological interferences of a highly advanced nature (towards this project) are MORE THAN likely.

So then that's why things are proceeding at the pace (and in the ways) that they're proceeding at now, I'm guessing. Waters are being tested at practically every single step, and decisions regarding when to move, when to pause, when to stop, when to move again, are being made accordingly as such.

A very, very, complex puzzle for them to solve given the sheer amount of entities (government, military, spies, big tech, big pharma, hedge funds and whatnot) and conflicting interests and numerous other volatile factors being involved in here (as part of the Grand PLAN), is what I feel as being the case in here.
