I'm quite sympathetic to what you're saying, what he did was very creepy regardless of legality. I merely take issue with the idea that 16 year olds cannot consent - most people seem to think they can if the legal standards is to be used a rough indicator of societal consensus, and I can also remember being 16. That doesn't mean I think it's OK for people to molest children or that adults structuring their lives around access to teenagers or children isn't likely criminal predatory behavior.
