I'm going to insist on no smuggled-in booze at my birthday venue
Why don't you want booze at your party?
Because I'm not having my birthday party at a bar so people shouldn't be drinking alcohol. I want people to be sober.
It's perfectly reasonable and understandable if you don't want to drink alcohol at your party, but not letting people make a decision whether or not to drink is controlling. People need to be able to make their own decisions.
There's no point in attending a party with any booze.
Not everyone agrees with you about drinking. Your mandate of no booze at your party is an attempt to control others and that is not correct. Give people the choices that they deserve to make.
