>One wouldnt care about DAD on loopback interface, because it's not noise on a wire, and it's not time consuming.

So how will you deal with a duplicate IPv6 address configured on a loopback interface?  As I said in my example, a router is using the IPv6 address on a loopback interface to source packets and a duplicate is detected - the network breaks down.
