that's correct. libp2p is designed as an agnostic library that could be used in projects similar to Mycoria. it offers the building blocks to build a p2p network.
as a side-note, I've tried to use libp2p in the past, but ended up writing transports, NAT traversal, and fundamental structs for my p2p network from scratch, ditching libp2p.
I would have thought libp2p is library enough to not be comparable. Am I wrong?
Mycoria is a ready-to-run software.
