No, they are trivial to block using techniques like deep package inspection.
In addition to that, they aren’t truly decentralized (no decentralized network really is), both rely on relay/bootstrap servers to start up the connection. So, if you block the public relay/bootstrap servers, you effectively block access to the network.
Tailscale, netbird also can traverse NAT.
Iroh (the actually pretty interesting software which the vibecoded rayfish is based on) and Yggdrassil do have their uses, but evading blocks isn’t one of them.

Keep in mind they can only “traverse NAT” if you have a publicly reachable node available, otherwise peering can’t complete. The Yggdrasil network maintains a handful of public nodes for this purpose, or you can set one up yourself on a VPS etc. But you still need to deal with this.
