Yes, I agree that NOS will give you the same power, but.....
1)when the bottle runs out, you're back to square 1. Run the hills all day on an 1050 cc BB, you'd need 20 bottles of NOS on an 800 to do the same thing, you can't carry enough NOS with you to equal the performance over the long haul, maybe to make the last 50 feet on the hill, or for the extra burst of track speed, but once you're out, the guy with the big bore is gonna leave you behind
2)big bores (without NOS) make more power from idle to max RPM, not just on the button. Making more HP across the board has so many more benefits IMO. Being able to clutch for one powerband vs. for stock and then on NOS is far easier, you will always have some compromise in clutching/gearing when running NOS, on any sled, big bore or stock but if we are just comparing big bore no NOS to stock sled with NOS, the win goes to big bore in my book. Not knocking any stockers with NOS, I agree that it is a good system if what you are looking for is a simple, instantaneous power increase and the cost is great for the power you get. Cost wise, big bores are more, yes, but your power supply is not limited. Also, the development time of a big bore is expensive, a company needs to recuperate the development costs, higher prices on the big bores, as stated, this makes NOS look really attractive when you can have the same power (even for a short time) with very low input costs. Also, NOS can be moved from sled to sled easily, I would imagine its hard to get big bore Ski Doo jugs to fit on a Yamaha bottom end...
Likewise we can't start comparing BB's and turbo's in terms of costs, because the win goes to turbo's hands down. Cost may be more yes, but as stated, turn the dial up at elevation, and you have just as much HP as at sea level, you can't do that with the BB. If we are discussing why big bores are disappearing, yes, both reliable (keep in mind that I'm saying "reliable" in terms of modern performance with EFI and four strokes included) turbo power and NOS are probably contributing factors to the presence of less big bores.
Now, if you had a BB with a turbo and NOS............
