Firstly the reason for why its important to get the vaccine it is because not only reduces your chance of being infected,it also contributes to community protection reducing the virus from spreading more and more. therefore getting the vaccine is important because now in all places such as schools ,restaurants ,stores and more public places are asking for vaccination cards.
The government is trying to get all the people to get vaccinated that's why there putting all these mandates because they want to keep everyone safe and reduce the spread of covid-19. For the people who aren't vaccinated the government isn't forcing them but just is pushing them into getting it because in all places it would start to require it without the vaccine you wont be able to travel or be with family members and it will provoke more deaths.
