This is like asking why if seatbelts work, we don't let people drunk drive (obviously drunk driving is more dangerous than being unvaccinated, not claiming it's a perfect 1:1 analogy, before people complain, just making the point that just because we have safeguards doesn't mean we can ignore the core issue).
Vaccines and masks work, but they aren't 100% effective. The effectiveness of vaccines is far higher if everyone who can be vaccinated is, as the protective effect is multiplicative.
There are people who can't be vaccinated, or who are at higher risk, and people who are just unlucky. They don't have a choice. They are affected by other's choices. The "personal responsibility" narrative is nonsense when it comes to communicable diseases.
