12 Mil put into the airport and a couple of mil a year to run it !
For that kinda money I have a more efficient way of making sure the islanders have prompt transport service. 12 mil would buy about 250 decent used 172’s and the annual few mil field operating costs could buy them the avgas, so dish out a Cessna and a ppl to each family on the islands and tell them to have at it
The only issue may be the better educated and more style conscious amongst them may demand a Maule instead of Cessna
