It seems like no matter what you do, it will always be possible for someone to tap into a wire or node between point A and point B (unless some revolutionary point-to-point information teleportation is invented). So isn't the next big thing just the strengthening (or proper application) of encryption?

Otherwise, how can a "decentralized, infrastructure-less" system really guarantee any privacy beyond simply making it more of a hassle to wiretap?
