FWIW, my opinion is that para trained soldiers are required for the multitude of scenarios in which a conventional fixed wing landing cannot take place and which is beyond the range of helicopter insert. Jungles, mountains and tundra come immediately to mind, there will be lots of others. Statistically unlikely I'll grant, but never say never.
Netheravon has sufficient helicopter activity for it to potentially be a conflict of interest were it to be the only DZ. WOTG could survive in the manner of Chetwynd ie no resident staff at all.
