Live and let live is not good public policy
“I don’t care what others do so long as they’re not hurting anyone else”
Obviously directly hurting others is bad and most would agree with that. But what about things that ‘only’ affect that person? People can hurt themselves psychologically (self-imposed isolation, addictions to porn/drugs/social media/etc), physically (drugs, dangerous driving, overly dangerous risk taking, overeating, bulimia, etc), and emotionally (codependent behaviors, addictions, etc).
The reality is that behavior you claim is only hurting yourself is never just bad for you. It is also bad for others. Others must deal with the consequences of you hurting yourself. Alcoholics and drug addicts very often say they don’t hurt others – but anyone who has a family member or loved one that is an addict would disagree.
Communities are often losing a valuable person with unique talents and things to offer. They aren’t able to live full lives or contribute their talents. Those are all losses to the person and to the world. In worse situations, it results in life-long health issues and more medical treatments that put stress on medical and emergency services. Destruction of property can lead to higher costs for things and higher insurance rates.
“I don’t care what others do as long as they’re not telling others what to do.”
It’s nice in thought, but the fact we live in a democracy with voting means we DO tell each other what to do in the public sphere by how and who they vote into office. That is why the truth about human worth and understanding what makes just laws and just governance matters more than feel-good measures.
