Politics is more or less the mechanism by which society takes collective action. Since people are broadly speaking in favor of free value, pretty much every policy that has nearly exclusively positive or at worst neutral effects has been implemented. It's not like anyone would oppose such policy! So "politics" exists as the realm of policy proposals that help some people and harm other people. All political opinions involve harming someone. If they didn't then they wouldn't be "political" opinions, they would just be opinions.
