In which case I consider your point to be void, and maintain that the UK driving licence is the gold standard of proof of address in the UK, i.e. is the most effective document for that purpose for normal daily life including contact with the Government such as DBS checks and checks conducted for official business.
If you wish to counter that point, evidence is the only sensible way to do so.
it really isnt this alleged gold standard you mention. People forget to change address on their license all the time and as such the last time i had to get some documents done they wouldnt accept it without another form of confirmation of my address because of that very reason
