You are right - it is confusing, welcome to the world of the CAA.
Sorry old chap, I think perhaps it's me that's confusing you! Let me have another stab it.
I agree that article 167 applies to you in your (and my) commercial endeavours. As you say, that involves ops manuals, demonstrated ability and so on.
The point that I am trying hard to make, for the benefit of other readers, is that nothing about article 167 suggests that it applies only to commercial operations.
If you fly and take a picture of your home for you own and others enjoyment then you are not going through a formal act, in which case you are not in conflict with 167
This is my problem. Where does it say that? Where is a definition in the ANO that taking a picture for your own enjoyment isn't data acquisition?
What I do know is without that Aerial Work Permission, I cannot fly for commercial gain. So by my definition articles 166 & 167 are the barrier to any form of commercial reward, I'm really not sure how else to put it.
No need to put that part any other way - there is no debate about that part.
We can play about with words and definitions all day long but the fact remains that these are the articles that apply.
I think this is what I am really saying - actually we can't play around with words and definitions!
So, I'll give it one more try: where does it say that 167 applies
only to flying for gain, flying commercial, etc?
