There are several concerns that warrant good encryption. Privacy for instance if you surf even with encrypted dns you still leak the sites you query (SNI). Depending in the traffic it can be known what kind of content you consume or even identify it explitly. Also there is the case of broken encryption. We got our fair share of ssl/tls exploits. Also the traffic inside your network is mostly unsecured or can you issue certificates for your NAS? (yeah you can if you do it right but who does that?) Your media libraries or samba/nfs traffic is probably unencrypted. Got in home security cameras connected over wifi? So yeah there are _plenty_ of reasons why you should have good security on your broadcast of your private data. Even if you got most of your lan in a VPN (which is a good practice tbh) your smart devices aren't probably in it.
