Oh, so, you do understand how herd immunity works, and just reject your personal role in it? Holy ***. That's so much worse.
It's not immunity, it does jack ***for others.
Because your only infected for two to forty eight hours, there is less time for you to spread the infection which lowers the total number of infected. You don't need the entire population vaccinated for this, not even half, and proper prevention and care achieves the same result without requiring forced vaccination.
Again highly misunderstood concept. Vaccinating people doesn't protect non-vaccinated from the virus. If you are vaccinated and come into contact with that virus, you will still contract it and if afterward you come into contact with another person, they will still contract it from you. If that other person is unvaccinated they will get sick, regardless of you being vaccinated. Your antibodies do nothing for them.
The only difference is that you will be contagious for a day or less instead of a week. That will alter how many total infections, but it doesn't "protect the old / young / weak". If one of them comes into contact with a vaccinated yet infected person it's no different then if they come into contact with a unvaccinated person.
Mass vaccinations are only really important in third world countries where living conditions are so unsanitary that epidemics decimate the population. Basic sanitation and clean living conditions make "herd immunity" a complete *** excuse used to drum of fear. "If Mr Burns doesn't get little Johny vaccinated then it will hurt my son Benjamin". Which is the line that has been pushed so far.
