I think the OP is a bit confused. Eastman 5222 in 4x5 is a special order item and this is the very first time that Kodak has offered it in any other size other than 35mm. It is a motion picture film.
Yes, the price of it being so high is because they have never cut it in sheet form and the issues in cutting a base like that, something kodak has never done, will cost more because of potential waste of the film during the cutting research period. Hence the up front high cost. If it happens (still need 6 more boxes ordered to make it happen) and it's a success, the price would theoretically go down, but also another special cut might not happen for a few years, and only if double-x still exists at that time. Get it while it's hot!
You can produce any look with any film in theory, some just have a look about it more naturally without a lot of fuss and testing.
I've never been able to get the look of double-x with people in any other film but Acros100. But again as someone else said, I scan, I don't print optically. And Acros is still expensive, $3/sheet not $6/sheet, but still much more than say FP4+/HP5+ at $1.32/sheet. Or Arista100(FOMA100) at $0.76/sheet.
Depends on what is important to you, quality vs quantity... And quality is relative, what are the qualities you want in an image, what's important for you to be worth buying.
