I didn’t make why that’s clear to bitcoin as obvious as I thought I did. But think softwar stuff.
Asymmetric cryptography makes it possible for us to keep our bitcoin safe because it raises the cost of executing an unapproved transfer to the point of infeasibility - even for nation states!
Similarly, the more people that claim to have orbited earth, the higher the cost is of keeping them all quiet. At some point even nation states can’t maintain the ruse.
