Even 10 years ago, there was barely a real need for DTV to exist in addition to NCL. The UK mainland has far more passenger airports than Germany despite its much smaller population and land area; there are simply too many passenger airports in the UK, and economics has simply asserted itself over time
You may be correct in the fundamentals, though dual existence or not, is now largely irrelevant. What you totally miss is that one can have far fewer number of airports supporting far larger areas of population as long as they are served by a
fully integrated transport structure, something the North East as a whole has failed abysmally in this respect, then any comparison with Germany in particular is meaningless !!
As a starter for ten consider their road & rail transport infra structure.
