That has been discussed conclusively on here multiple times before and no doubt will be again, but he briefly discusses that in the below paragraph, albeit vaguely:
Is there a wish to become a holiday passenger airport again?
If the commercial opportunity were to arise in terms of interest from an airline with a clear demand from the public and the companies in the area for a route then the answer would be yes.
Edit: After reading the bit you quoted again, it seems the answer to your argument is in the paragraph you quoted when he mentions about needing flights in volumes.
