Doesn't work that way. Licenced paintball fields didn't "raise" mass opinion, licenced paintball fields was in part a reflection that the public had nothing against paintball. Also, there were enough paintballers around to make it financially viable, there are too few airsofters for the same type of fields paintball has. Not to mention there were relatively few legal issues surrounding paintball, where as there are certain legal issues with our equipment that makes our situation less than ideal.
Finally, paintball does not have the same inherently unfavourable image we do, what with our paramilitary, look-they're-right-wing-nuts-in-training fashion versus their BMX, is-that-a-kidney-on-top-of-their-paint-sprayer fashion.
