Are you saying that there are people - lots of people - who will not be infected with covid if they are exposed to it? That seems to me to be what you are implying. That would be news to me.
Also since you asked the answer yes, it appears many people with T cells from previous coronavirus many time do have a pre existing natural immunity.
“Importantly, we detected SARS-CoV-2-reactive CD4+ T cells in ∼40%-60% of unexposed individuals, suggesting cross-reactive T cell recognition between circulating "common cold" coronaviruses and SARS-CoV-2.”
Long ago - in covid years - the original version of the virus gave better protection than vaccination against getting reinfected. These days getting vaccinated after surviving the virus and full recovering provides better protection against reinfection, and at the same time it reduces the load on the healthcare system so that people who need care for their unavoidable health problems have a better chance of getting the help they need.
having natural immunity is superior to immunity from the vaccine alone
Natural immunity is helpful if covid doesn't kill you while you're acquiring it.

"this analysis was conducted before the emergence of the Omicron variant, for which vaccine or infection-derived immunity might be diminished."
"evidence suggests decreased protection from both vaccine- and infection-induced immunity against Omicron infections, although additional protection with widespread receipt of booster COVID-19 vaccine doses is expected"
"vaccination remains the safest and primary strategy to prevent SARS-CoV-2 infections, associated complications, and onward transmission. Primary COVID-19 vaccination, additional doses, and booster doses are recommended by CDC’s Advisory Committee on Immunization Practices to ensure that all eligible persons are up to date with COVID-19 vaccination, which provides the most robust protection against initial infection, severe illness, hospitalization, long-term sequelae, and death." https://www.cdc.gov/mmwr/volumes/71/wr/mm7104e1.htm

That's from 2020 Jun 25. Long before the Alpha, Beta, Gamma, Delta, and Omicron variants.
“People who had previously been infected with COVID-19 were better protected against the Delta variant “
The Delta variant is not currently a factor. See the 'Percentage of Cases Caused by Different Variants in Ontario' graph at https://covid19-sciencetable.ca/ontario-dashboard/
you want to bar people from society even though they have a superior immunity to those who can move freely
It’s evil

The rest is just political noise.
