It's not true.
The higher the community spread is, the more often you'll be exposed to the virus.
The more often you're exposed to the virus, the more likely you are to have a breakthrough case.
Having a breakthrough case greatly increases the risk that you'll have some lingering effect, even if the chance of a serious impact is smaller.
Hence, the chance that you'll lose your sense of smell as a result of a breakthrough case resulting from higher community spread is directly related to the actions of others and their choice not to vaccinate.
The fact that we cannot vaccinate "everywhere in the world at once" doesn't change the fact that you're personally going places where we're also not vaccinating enough. Like, say WDW, the mall, or MCO airport.
Time is not on your side here. The longer we go with high spread, the more often and larger number of times you'll be exposed to the virus.
You could do other mitigation efforts to try and reduce that exposure beyond just the vaccine. But, they're not nearly as durable as everyone being vaccinated, they're subject to mistakes, the risk of a mistake goes up the longer and more often they need to be done, and as you've said before, they're just a pain and something nobody really wants to do.
As much as you want this to be an individual responsibility thing, it's not. It's a group project, and the group members not pulling their weight are a direct threat to others.
