"And for another, pointing guns at people is hardly a solution to funding and is a recipe for funding things that should not be funded. Also a recipe for people being shot or scared."

I assume that by "pointing guns" you mean using voting to decide the appropriate amount of funding for certain goods like funding for research, expenditures for the military, production of roads, and funding for charitable giving. The overwhelming majority of rich people (and the rest of the country) will not vote for libertarian systems of economic and governmental organization. People (even the rich) favor utilizing democratic rule in many situations. So the people who pay most of the taxes (the rich) must "want" to have a "gun" pointed at their head to have money "involuntarily" taken from them, because they consistently vote for democracy!

More likely, Americans and other free people perceive that libertarian forms of economic organization are so inefficient at providing certain goods and at providing morally acceptable societal outcomes, that those advocating such an awful politico-economic system, are perceived as trying to point guns at the rest of us!
