You have unfairly lumped Libertarians in your rant there. Non-agression is a fundamental principle, just as is supporting a large standing military is not supported. I agree that Republican's support of a large military isn't ideal, but liberals/socialists are also keen on using force to oppress and subjugate, i.e., using force to require taxes be paid by a populace, for the 'greater good', as defined by the oppressors.

However, there's decent support for the concept of basic income within the Libertarian circle, as it can be seen to enhance liberty and freedom - though there is the whole challenge of the funding coming from taxation to get around :D A search for 'libertarian basic income' will yield good info.

A great analogy around the thinking of a Libertarian - "Is it worth pointing a gun at someone to force them to fund my plan?" Remember, all governments must resort to force to enforce their agenda.
