> it’s not financially viable when there is ample land for farming.
I've not heard of it being financially viable even when farmland is very constrained - say, in Holland.
The numbers probably work on the ISS, Moon, or Mars...so those places will probably be "stars of the show", in the next round of hype which vertical farming companies use to bilk idiot VC's.
(St. Helena has a reasonable latitude and low population density - so at most you'd need some greenhouses.)
