Does encryption really make a difference there?  In most
jurisdictions, home networks use recursive resolvers whose operators
are required by law to provide cleartext copies to local authorities.
Encryption won't change that.

If it is about securing broadcast media, just run IPsec between the
CPE and the first ISP router with trusted ARP and routing tables.
