I don't think it is fair to say that the natural order of things is Anarchy.
We started on this earth with no political or social systems, and we've ended up with what we have today.
I think anarchy, in order to persist, has to be artificially maintained by some sort of outside institution.
If there isn't such an institution then history will simply repeat and in the long run we will end up once more with a sort of system like what we have today.
As for birth control or senior benefits, I wouldn't be surprised if more people are willing to fund the creation of an action figure once, rather than a repeating amount towards people they will never see or benefit from.
I simply do no believe that private charity can function adequately enough to provide for the needy.
Of course, I sympathize with the position of the above average successful person not wanting to be burdened with the needs of those less capable and successful than themselves.
It is truly terrible to have done well and then have the satisfaction stolen away from you by people who either aren't able or willing to do the same.
It is much harder to create rather than destroy.
"I think anarchy, in order to persist, has to be artificially maintained by some sort of institution."
Well, then, it wouldn't be anarchy, would it?
Exactly. Absolute anarchy, no matter how nice it maybe would be in the short term and how good the arguments are for that, is impossible to retain long-term. A government system will always develop. It always has, every time. Without any kind of systemic check on system-making, people will make a system.
