@Eiregoat @feld This is a bit of a tangent, but I tend to dispense with the right/left false dichotomy and focus more on how people conceive of "rights". There are basically two conceptions of rights, "dissent" vs "need".
The first is designed to protect one's ability to dissent without experiencing reprisal. Specifically "Take 'No.' for an answer in respect to other's person and lawfully owned property." That's where you get things like free speech, gun rights, freedom from unreasonable search and seizure, etc. The other conception is designed to protect people's lives and health, which is where you get ideas like the welfare state, universal healthcare and so on. It's essentially philanthropic.
However those two definitions are at odds with each other, because on the one hand, property rights tend to favour people's greed and selfishness, including established monopolies, whereas need based rights can only really be enabled through state sponsored theft and extortion, which in the extreme scenario transfers wealth from the productive members of society to the freeloaders.
But I think there is still a middle ground. What needs to happen in my view is to place a limit on the amount of wealth an individual can accrue, particularly insofar as it poses barriers to others' access to the needs of subsistence/prosperity. It should never occur that a single person or group (eg. corporation) owns all the farmland, for example. Nor drain an aquifer or otherwise prevent others from accessing potable water. And so on. If there is to be a rules based society, then there needs to be reasonable limits on the amount of natural resources which can be taken out of the public sphere and made inaccessible to those who need them for life, liberty and the pursuit of happiness.
Conversely, taxation should not be allowed, because that's simply a euphemism for extortion. Instead there should be crowd funded ventures which people can subscribe to voluntarily if they want the associated benefits. One possible exception to that is military service. The one role of government which is indispensable in my view is to defend the community from external threats. While I don't necessarily support conscription, I think that military training should be a required part of the educational curriculum and a criterion for membership in the community concerned. That includes making reasonable contributions to provide necessary material supplies (arms, armour, etc).
If I have one criticism for right libertarianism is that it tends to focus too much on person and property, without paying any attention to the inevitable inhumane consequences of allowing that to go to an extreme. Similarly when it comes to left liberatrianism, there's too much in the way of saccharine platitudes about the common good and equality, while disregarding that it can only truly be based on the individuals' right to dissent from the group. Equality shouldn't focus on people having the same outcome, but on everyone having the same opportunities without artificial legal barriers. The rest is up to individuals to sort out between themselves based on mutual goodwill without use of force.
