It's really not that bad.

Gotta refill the gas tank pretty often, too. Yeah, everyone hates constantly shelling out money for gas, but does that keep them from driving?
I look at bottle refils the same way as refiling the gas tank, or topping off fluids. Necessary evils.
And on another note...
Yeah, you have to keep paying for refills...but, it's not like the money stops after the install with forced induction either. You burn more gas, maintance costs go up, etc, etc.
You also burn more gas and have more maintenance with nitrous as well so that's cancelled out. Let's take my turbo car against your nitrous car and see how things look between passes. You're changing out bottles, refilling bottles, heating up bottles, etc... meanwhile, I'm kicked back eating a hot dog and enjoying the races until my class is called back to the lanes. While staging, you're having to make sure line pressure is good, purge the system, etc... I just grab the staging brake, bump into the lights, 2-step, and go.
Let's say you make 8 passes that day down the 1/4 mile, 4 passes per 10lb bottle (cause more than that and you're losing power and ET on the same bottle). At $4-5 a pound, that's $50-60 of nitrous you just burned through. Meanwhile, my turbo cost me nothing extra. We burned through similar amount of fuel, same type of fuel, etc... Of those 8 passes, your nitrous car is going to start having some issues after that 4th pass on the same bottle as the pressure starts falling off more and more with the bottle going empty and your ET and MPH suffer. My turbo car on the other hand does the same thing every pass.
Let's say on one or two passes, you have a mental lapse and forget to turn on the nitrous. My turbo takes that user error out of the equation and won me a couple easy races. There's always a couple people that make that mistake every time I'm at the track. If I want more power from my turbo, I can push a button a couple times on my controller for more boost and more power. Meanwhile, you have to pull your car off to the side and change out parts.
Let's take both of our cars out on the street. We're on on-ramps getting on the highway and it's short one so we want to get up to 65-70mph fast to blend into traffic. With my turbo, I can ease the throttle down a little bit, make a few pounds of boost, and be right up to speed in no time. Your on/off switch like nitrous system can't do that, even if you had it primed/purged and ready to go. We're cruising down the interstate and get stuck behind an truck going 55mph. I can leave my car in 5th gear, put the throttle down halfway to build a little boost, and zip right on around without downshifting or taking the motor over 2,500rpm. Your nitrous can't do that. We're driving along and an Evo pulls up by us wanting to race. Oh no, your nitrous bottle isn't heated up, system isn't purged, etc... well, my turbo is. Turn the camera on and watch as the turbo cars show you the satisfaction of always having full power on tap at anytime.
