I'm afraid you're fighting a philosophical battle here; in such cases, casualty rates are appallingly high.
I like to tinker with libertarianism as much as anyone here, but to get down to action on specific solutions? Nada.
It's one of the reasons I will never join the LP. it's a perpetual debating club with no ability to get beyond its own arguments and engage in genuine policymaking and power-sharing.
But don't entirely lose hope. Day by day, the real crimes of the supra-wealthy elites will become so blatant, so hard-core, that even the sophists of the LP will wake up and realise there is only one way to deal with it:
Fight to gain control of the government they loathe so much, and use it as a weapon against the plunderers and thieves.
And, if they are as principled as they claim, they will reduce its powers and set their own powers aside.
