When have I knocked the argument for buying the £30 lock that I have? Please show me.
I don't think my argument has come across to you correctly because you have been coming at this from a place of defence and assumption, and haven't been listening properly to what is being said.
You can't see that you can get a comparable lock as a gold-rated SS lock that isn't rated. Or that you have paid a premium for your locks for a stamp on them that in reality is only worth something to the manufacturer who has got that premium out of you and to you if your insurance company insists on gold-rating. Surely you can see that there's something wrong when a cable lock (one of the easiest to get through) is in the same rating as a small D-lock (one of the most secure)? Both of these types are in the gold-rated list. One is far better than the other.
This is gold rated-

Used properly, it's very difficult to overcome.
This is also gold rated-

But you're saying that a gold-rating is sufficient for your satisfaction.
So unless/until you can get past that then yes, we are at an end.
People need to know which type of lock are good in which circumstances. They need to know how to lock a bike up properly. Relying on a part-security-part-marketing rating as a sign of resilience is dangerous.
People also need to know what the insurance options are, and that you can very often be wasting money going to cycle-specific insurers.
