Some things people want to do may cause harm to other people. For instance, smoking in a bar could cause physical damage to the people around them force to inhale the secondhand smoke. For this reason it is acceptable to curtail individual rights if it is in the best interest of others.
It is not acceptable to curtail individual rights even if it will benefit society. There is a certain cost and risk of freedom which is often more than we wish and in turbulent times the subject of curtailing individual rights always seems to come back up. The problem is once we have relinquished our rights it is much more difficult to get them back, and we would really miss them.
