Why? Why do I have that duty
Because your fellow citizens, the courts and your insurance company say that you do.
Do I have a duty to provide them with armed guards?
Depends, but potentially.
Do I have a duty to offer breast cancer screening at the door? Do I have a duty to make sure they have their government mandated vaccines on the way in? Do I have a duty to make sure they are eating a healthy, balanced diet based on the government food pyramid?
Outside of possibly California, no, unless Obamacare is implemented.
Are you incapable of checking for an acceptable number of fire doors before you attend a live concert?
No, but if I invite the public into my property then I have the duty to ensure that the fire code is complied with.
State fire code=perfectly consitutional and no problem; state fire code being used arbitrarily=problem.
