That only works when only a couple of governments are involved. Once (big if!) it becomes a free for all there is risk that you will send supplies and someone else will use them. Or maybe they just charge a ransom before you can get at your supplies - just send a robot out to where those supplies are going, "hide them", and ???. There are too many risks to trust that someone doesn't think of this.

I hope the rocket scientists are not caught as off guard as us computer people have been by ransomware and the like (note that viruses have been doing evil things for over 30 year and we still don't have a handle on it)
