To prevent yourself and others from getting (the severe form of) the virus. I can assure you that most people would still have gotten vaccinated.
Personally what I would like is roughly what we've had in the UK for the previous few months. The ability to do mostly normal life, but with restrictions on large events and mandated precautions such as masks. Along with vaccinations that would probably have been a sustainable state. Unfortunately I strongly suspect that the complete opening up that we're currently seeing will only lead to further lockdowns in a few month's time. I would love to be proved wrong on this, but that's what it's looking like to me at the moment.
