Perhaps, but based on a similar experience I had with a Tibetan monk, I'd say there's actually quite a lot of room for flexibility. Just because someone has a handful of materialistic interests doesn't mean they're incapable of being a good person or teacher. That was probably the main lesson I learned from the monk I knew. As outsiders, we often have a very romanticized, storybook view of monkhood that doesn't line up with reality.
