I'm an anarchist; I think it's too important that humans have the ability to live their lives with dignity, and I'm fully aware of how infrequently that happens when anti-government is limited.
Practical anarchist, though. Gratuitous rebellion for its own sake is counterproductive.
It is necessary that humans come together in cooperation to accomplish goals otherwise impossible without cartels, to break the Nash equilibriums. But it is also necessary to dismantle and diffuse concentrations of power when they become destructive to their original aims. The more permanent an institution, the more inefficient and corruptible it can become as time passes. Corporations need to sometimes fail and be replaced by scrappy startups. Governments need to sometimes hand over power to a different political bloc. Religions need to sometimes have ideological schisms. Statues and monuments sometimes need to be taken down and warehoused. Perfectly good uniforms sometimes need to be replaced with different designs. Sometimes, the fortunes of the rich need to be squandered, stolen, or sunk.
The impulse to rebel must be satisfied, and one would hope that it is possible without violent rebellion, but that is sometimes unavoidable, if the entrenched power structure in question proves unwilling to diminish itself peacefully.
As it is now, my primary concerns are the increasing concentrations of wealth to fewer people, and consolidating ownership of communications media, broadcast and network channels, and intellectual property. These are self-reinforcing, and can lead to a runaway, much like increasing atmospheric CO2 can trigger a runaway greenhouse effect. The healthcare/health-insurance industry is a potential future threat, but it isn't yet too late for them to sort themselves out through rational analysis and discussion.
