I can explain it to you(again) but I cannot understand it for you. It, the smoking ban, relates to the other regulations because it is a government imposed limitation on the property owner's use of his property. Many such regulations are imposed on businesses all the time by an over-reaching government and they are often established so as to affect an existing clientele. I hope this is now clear to you. I would have thought the point was obvious to but apparently not so for everyone.
There is a difference between the things you listed and a smoking ban - the smoking ban is a limitation on the clientele the owner is permitted to cater to - and it matters not whether he has a liquor license ornot.
