If only the guns and ammo was the only expense, I'm pretty sure most of us dont live next to a paintball/airsoft range. I'd have to drive 1.5 hours to the nearest one.
With a sim you can eliminate all the hassle that isnt much fun.
Travelling to and back, getting your shit in order and cleaning your shit afterwards stops being fun after you've done it a hundred times.
Not to mention the scope, if you want to have large scale battles with air/paint guns you'll propably have to wait for some large event in another country and that shit costs more than a decent PC real fast.
