In fact, full network encryption isn't a goal per-se, but a requirement. The main goal of Yggdrasil is to bring decentralized routing to the table, thanks to DHT. In its current state, internet (while being a mech network) is based on centralized routing, in the sense that the ISPs are responsible for routing their clients to other destinations. With Yggdrasil, every single node (your laptop, my phone) is a potential router to any destination, without you even knowing. That's why encryption is needed: the whole network is untrustworthy, and if traffic isn't encrypted, anyone can potentially sniff your packets.
