None of your logic is valid if everyone gets vaccinated as it will be "as good as it can be". Some non controllable number of people will get the disease, but the number of people in ER and ICU will be way down and they can get the help they need instead of help from an exhausted, overworked ICU department that is far from in optimal condition to handle you and other non-covid emergency cases. Your "logic" simple falls apart at the seams.
