Well, sure people can make their own risk assessment for themselves but herd immunity is not just about thinking of the self. I live in an area wide a significant anti-vax (and even anti-“Western medicine”) population. It puts everyone here at risk. It has put their own children at risk (a couple is currently on re-Trial for the painful, horrific death of their child from meningitis because they chose “alternative therapies” over medical attention)
Again, quoting from cdc.gov:
Chickenpox is a highly contagious disease caused by the varicella-zoster virus (VZV). It can cause an itchy, blister-like rash. The rash first appears on the chest, back, and face, and then spreads over the entire body, causing between 250 and 500 itchy blisters. Chickenpox can be serious, especially in babies, adolescents, adults, pregnant women, and people with a weakened immune system. The best way to prevent chickenpox is to get the chickenpox vaccine.
Chickenpox used to be very common in the United States. In the early 1990s, an average of 4 million people got chickenpox, 10,500 to 13,000 were hospitalized, and 100 to 150 died each year.
Chickenpox vaccine became available in the United States in 1995. Each year, more than 3.5 million cases of chickenpox, 9,000 hospitalizations, and 100 deaths are prevented by chickenpox vaccination in the United States.

Serious complications from chickenpox include:
Bacterial infections of the skin and soft tissues in children, including Group A streptococcal infections
Infection of the lungs (pneumonia)
Infection or inflammation of the brain (encephalitis, cerebellar ataxia)
Bleeding problems (hemorrhagic complications)
Bloodstream infections (sepsis)
Dehydration
Some people with serious complications from chickenpox can become so sick that they need to be hospitalized. Chickenpox can also cause death.
Deaths are very rare now due to the vaccine program. However, some deaths from chickenpox continue to occur in healthy, unvaccinated children and adults. In the past, many of the healthy adults who died from chickenpox contracted the disease from their unvaccinated children.
Not having 100 deaths appears to me better than 100 deaths. And that does not account for those who may be permanently injured due to other complications like encephalitis.
