The goal posts keep moving.
First iroh was marketed as "solves communication behind NAT". Then we went to application level NAT busting vs node level NAT busting. Then we went to distributed vs client-server, then we went to stable IPs for non-server devices (your original comment).
Now we moved to "true peer to peer" and "public keys".
This just tells me that the marketing site doesn't explain what Iroh actually does.
The fact that so many other people (apart from me) asked about the connection to Tailscale is also interesting.
