"...totalitarianism behind vaccine passports..."

Problem: An ongoing pandemic, requiring greater or lesser levels of isolation.

Solution: A vaccine. Vaccinated individuals are much less likely to suffer the ill effects of the disease and to transmit the disease. Isolation is no longer necessary.

Problem: Large portions of the population refuse to take the vaccine. Isolation is still required for this portion.

Solution: Allow those who have been vaccinated freedom from isolation.

Problem: TOTALITARIANISM!
