Not sure what this statement means. Government facilities/buildings already can't be limited unless there are 'court' facilities involved. (Agree, 'school' gun-free zones need to be worked on...).
But concerning the vast majority of what *I* think you're talking about, that's PRIVATE PROPERTY even though they may be open for business to the public. I'm a big believer in the supremacy of private property rights and I sure wouldn't want the government mandating who I have to let onto my private property (even though they do it, in the case of race discrimination). And this argument of trying to hold the shop owner responsible for one's safety against an armed robber is just ridiculous: no one forced you to go into their shop. The solution seems clear to me: don't patronize their establishment (vote with your feet; go somewhere else). Oh... and leave one of those cards to help them see the light!
