Your logic does not work. If people in a developed country would simply become vaccinated and boosted, then only the vaccinated or not condition would typically apply in mainstream society--and not the 3 other above conditions.

While all 4 are discriminatory, the first 3 are not inherently due to personal choices or preferences. People choose not to get vaccinated harming society as a whole--and make the other 3 above conditions come into play.
