If you are collectivist, you are leftist. I am becoming more right wing, as in no government. Not fascist, that's leftwing because it is collective in nature, no I becoming more anarchist as I get older.
Government is power. Power to either help people, or abuse them. The historical record shows that overall governments have been far more abusive than helpful.
In that case everybody is a leftist because all humans are collectivist. Very, very few aren't. The Unibomber wasn't but he still needed others to survive - he travelled by bus to deliver his bombs on roads made by other people. He bought food. Didn't appear to buy clothing though. Everybody needs at least a couple of other people to get by - whether that person is supplying you food via the grocery store or your electricity via the utility worker.
Government is needed for there to be a inkling of civilisation. Sure, some govts might as well not exist - Somolia comes to mind - however most of the other govts are working to one degree or another. Flawed, and could be better, but there is one big thing interfering with the perfect govt - human nature and how we all think that our own personal version of how a govt should be run is the perfect solution.
