> Maybe I am misreading what you are saying, but I didn't say taxation was immoral. I said it's immoral for me to vote to impose a tax on someone else.
The distinctions you're making only make sense in the context of radical individual libertarianism. "We" are imposing a tax on "our" members as a condition for belonging to "our" community. If I vote for a millionaire tax, and strike it rich tomorrow, I'm subject to the tax too.
> If everyone in a society agreed to something, then fine, you are not forcing someone to do something. But if not, then it's not "sanctioned by society", but rather sanctioned by a subset of society.
Again, that's a pointless distinction. Society inherently operates through collective action, and collective action is inherently majoritarian. Organized society only exists because the majority forces the physically strong to respect arbitrary concepts like "property rights" and the "right to life." Society does this for the greater good, but make no mistake that there are a lot of people who are worse-off under this system (Zuckerberg isn't one of them--think the big burly moving guy who occupies a very different place in our society than he would in the state of nature).
> The US Constitution was written to protect the minority from the tyranny of the majority.
No, it was not. The Constitution put in some safeguards to protect individuals from the majority, but most of those protections aren't even in the main text but rather in the Amendments. Article I of the Constitution is an elaborate exercise in defining the metes and bounds of majoritarian rule through a Congress elected directly or indirectly by the majority. Most of the founders were not radical individualistic libertarians, but rather people who believed strongly in the rule of law and the institution of government (the Constitution was a reaction to the Articles of Confederation which was deemed too weak of a government!). It was framed by people who regularly invoked the language of the collective (the first words are "We the People"), and were from a legal tradition where absolute sovereignty was vested in the government.
