The problem is: without doing that (having repositories access in the domain model) we sometimes fall again in anemic model problem, putting behavior in different classes of the data, and so on.

We use builders for all our domain objects and inject a stub repository (in practise we use the lovely Mockito for the stub) by default. It's easy enough to specify through the builder if you want to use an alternative stub/mock if necessary to test behaviour. Looking back on the talk, I probably should have made it clearer that the point was more that I think there's a risk of being dogmatic about the implementation when what matters is how you can make your code reflect the shared model.
