But many people are part of a family or a group of people in some way, and gambling, alcohol, drugs “that only hurt themselves” tend to also hurt other people.

But many people are part of a family or a group of people in some way, and gambling, alcohol, drugs “that only hurt themselves” tend to also hurt other people. If we are going to be liberal, we also need to ensure society as a whole isn’t damaged in the process. War on drugs, as an example, have more or less destroyed other countries. Legalised drugs are probably better, but could be taxed and those with problems should be treated as they have a sickness. Gambling could be state run and be handled the same way.
