Yes, very frustrating this. I totally agree that all ISO standards - in fact, all standards and all laws - should be freely available. Nothing else makes sense.
The obvious solution is to simply copy the text of the standard into the legislation that relies on it.
But many standards that people need to be able to refer to are not referenced in legislation; this includes many standards that are needed for interoperability. In that respect, ISO is providing big companies with an anti-competition 'moat'.
