Think of it more like a drivers license. Proof that you have passed a written test, driving test and an eye exam. Includes your full name, home address, photo and DOB. The Excelsior Pass has less info than that. And will only be required for entering private property from which people can already be barred entry for arbitrary reasons.
Again - you cannot require a driver's license to cross state lines. Precisely because you cannot be required to present that information in order to move about freely. As long as you aren't the person driving ;)
I understand that this is not inter-state travel, but at the same time you cannot be required to provide your identification by law enforcement or others without cause within them. It is not illegal to walk about without documentation as to who you are.
You aren't even required to show identification to walk into a tobacco or liquor store - only to purchase.
Certain government buildings, bars, clubs, and smoking lounges are the only exceptions I know of to this rule. There is no compelling reason to expand that list, nor the information they are allowed to request.
You won't need to show a vaccine card to cross state lines, only to go out to eat.
Of course its okay to walk around without an ID, no one suggests otherwise. But if you go to a restaurant without an ID, and get carded you can't order your drink.
Is the restaurant obligated to serve you then? Absolutely not.
You can enter the state without a vaccine card, you just won't be able to enjoy eating out in all the incredible restaurants in the state.
