Under that rationale you're never safe in any situation from anything.
People are never going to be any safer from covid than they are once they have been vaccinated. Ever.
I'm not sure what you are trying to advocate here. Do you expect people to live in fear for the rest of their lives?
People need to get real here. If you're vaccinated, you're as safe as you're ever going to be. There's no point living in fear anymore - and if you're that scared of dying from covid, then you need to stop going to events where 30,000 people attend as it's a statistical certainty you will pass people with covid numerous times.
“ People are never going to be any safer from covid than they are once they have been vaccinated. Ever.”
That’s not the case though - there is one important factor that you have ignored and that is how many people in the general population are infected at anyone time.
As more and more people become become resistant to the virus, either through vaccination or having been infected by the virus, then the number of individuals in the general population who are infectious will fall.
We have not yet reached that point, indeed the number of reported cases is actually increasing not declining.
Relaxation of the anti-Covid precautions is helping the numbers to rise and it can be argued, on a selfish basis, that this will shorten the time until the maximum level of herd immunity is achieved and numbers have fallen to the minimum level. That however does not mean that at this point in time if you have been vaccinated then you are as safe now as you will ever be - you aren’t.
