Potential issues? What potential issues could there be with people running faux bars in their own home without a liquor license? Why not go all in. Run an app to let people invite strangers into their house and do major surgery/critical care on them. Call it AirAandE. After all the obvious evidence to the contrary, why do people think this "who needs laws what could go wrong" approach will work out?
The sassy tone is really not necessary. Also, airbnb's entire business is predicated on inviting strangers into your house. Do you have anything else?
(B) Airbnb "hosts" don't invite people and then serve them alcohol. There's no way this brilliant idea doesn't run afoul of liquor laws.
