Government programs IS US HELPING EACHOTHER. Sure corporations have been undermining democracy, but the government is OUR corporation. It's the only one that we get the choose what it does. The fact we're obligated to pay taxes is EXACTLY the implementation of your statement "we're obligated to help eachother"
I don't understand how you can make statements like this. The threat of violence? The government's monopoly on violence is rephrased as the will of society to ban violence in public life by restricting violence only to the enforcement of democratically selected laws. There is no other way I can conceive. Should more people have the ability to use violence to enforce their views on others? Should corporations have that right? If no one has that right how can we stop someone who decides THEY have that right?
The whole "government monopoly on violence" is for me the most absurd librarian statement of them all. What's the alternative? Who should decide what deserves violence? Who should use violence? What do we do if someone breaks this compact? Because the current answers are at least ideally "the people, through democratically enacted, clear and transparent laws", and "the people, through the police they pay for accountable only to the people" and "apply fair and balanced justice through the judiciary system, run by the people and accountable only to them". I'm in no way saying that it's working perfectly as is clear in recent politics, but it's certainly trending in the right direction in social democracies. We're closer to that ideal now than we have ever been. As far as I've seen libertarian ideology has only come up with absolutely HORRIFYING answers to these questions, or wishy washy nonsense.
