I see this as the logical conclusion arrived at by reasonable people, acting reasonably.
There needs to be a way to ascertain:
- Who is infected (and thus, contagious)
- Who has had the vaccine (and thus cannot be infected)
- Who has had the disease, and now has recovered AND has developed antibodies (and thus presumably cannot infect others).
Yes, "your certificate, please" grates against our love of personal liberties.
But in a time of public health crisis (disease with as-yet no vaccine) such liberties will have to yield just enough to accommodate the need for public health.
We're "asked for documentation" in various situations:
- Officer asking for license and insurance at traffic stop
- Proof of insurance required by DMV before registering vehicle
- ID required for voting (at least in some states, should be in ALL of them)
- Proof of vaccination to register kids at school. (I'm guessing private schools require same proof as do public ones)
The last one is particularly important. Would you want your kids (even if they had been vaccinated) mixing with kids who carried no protection against polio, measles, etc. ?
If you were an employer, would you want employees who could be contagious, working alongside the healthy? You might be subject to a lawsuit if you had a worker become severely ill from COVID who then alleged that you had not required returning employees to provide proof that they were either vaccinated or had had an antibody test. This is going to happen... wait and see.
How many have see the film, "Contagion"?
Remember what was done with folks who received the vaccination towards the end of the movie...?
