The second amendment and helping the needy are offshoots of the core discussion of natural rights.
You are addressing societal goals, not rights. It is a societal goal to be able to help the needy, and obviously to make the process completely moral and not hurtful to anybody it would require a system of completely free and willful exchange in order to realize that goal.
I guess the issue of rights is germane to the topic of helping the needy because just about every society decides at some point that the goal is more important than the natural rights (strictly construed). We tax, which strictly speaking is an involuntary exchange and against any construction of natural right that I know of, in order to realize the goal of helping the needy.
Sorry, but that's not correct. Taxation is passed by elected representatives, and that election is the point of consent.
We could say you also have the freedom or choice to move to another country if you don't like the taxation here, but I won't go there.
You know what's unnatural? This absolute idea of 'private property'. Why is it one family can own more than 100 million or more of their fellow citizens? Why is it that all land in the US has an 'owner' so that people can't go live on it without the owner's consent? The point is that some balance is needed between the extremes of an extremely high concentration of wealth turning most citizens into wage slaves to the few who own the resources, and too little 'private property ownership' resulting in a poor society.
Your argument all taxation is some violation of people and somehow a bad thing is an extremist ideology and quite unworkable as a practical matter, with no useful place in policy discussion. The question is not whether to tax, but who to tax for how much and what to do with taxes.
We restrict the ownership of a piece of property (a gun) in order to realize a goal of lowering deaths.
Ideally we would be better off truly loving our neighbor and helping the poor, but in the meantime we set up a system that takes the individual love out of it and replaces it with contempt because we are technically having our natural rights violated by being coerced into a societal framework against our will.
Again, that's not correct. Love is expressed through the democratic process when people select policies, and pay for them, which are helpful to others, and where people recognize that there are all kinds of areas, from putting a man on the moon to funding basic medical reserach not otherwise profitable, where the government plays an important role and can get things done better than the private sector or charity.
And again this 'against our will' part is contradicted by our elections. Now, I'm all for election reform that reduces the validity of those elections, but that's a different issue.
As to the second amendment, I don't think it's partisan at all to think of it as a natural right, a gun could be created through the labor of a single man, so under what understanding of natural rights would he not be entitled to that?
You're replacing 'God-given right' with 'natural right', I did not do that. But a couple things.
You mention it can be created by one man's labor - why is that relevant? If two men collaborate to make something, how is that less of a 'natural right'? Or 10,000 men?
Second, what if a single man makes a bunch of pressure cooker bombs? Makes a bunch of Ricin or another chemical weapon? Are all these 'legitimate' to own because he made them?
It's just a bunch of nonsensical parameters around the issues that have no practicality as to what is good for society.
There are very important issues to discuss around political rights and freedoms, but those aren't them.
