Ok, there are millions of addresses in the LAN, but for example when you send an email that IP is known. A determined attacker wanting to attack me will find out where my printer is.
You don't send an email to an IP address. You send it to an account on a server. Also, with IPv6, a LAN has a gazillion addresses (2^64 or 18.4 billion, billion).
And the server writes your home IP into the received headers. At least some servers do. This is yours: Received: from ?IPV6:2607:fea8:4c82:5900:...?
