Is it perhaps that you trust the access network, but you are concerned
that someone between you and your ISP could spoof the comms? Even with
HTTPS, etc., we typically use SSL/TLS to protect our connection to a
service we already trust somewhat. I totally agree that if one cannot
trust an ISP, then there is no point even if it offers encrypted DNS.
Just my two cents.
