I mean, right-libertarians just act as if their first principles ethical stances are self-evidently true. And concerns about things like the problem of collective action are irrelevant. Even more bizarre, is they assume that everyone is going to eventually agree with them and have a moral awakening where they realize "taxation is theft" and therefore we have to get rid of the welfare state.
Discussion
You get rid of the welfare state by outcompeting it. I see stronger individuals forming stronger communities that protect the rights of the individual as the basis for any working community/society.
And at the same time become better at articulating and communicating what is a common good that benefits each individual directly or indirectly through voluntary interaction/funding.
I don't see one win over the other. I see a powerful dance instead of a existential fight.
If I have a bunch of healthy body parts needed by 10 other people, and their "collective will" is to sacrifice me to save themselves, does that make it morally okay?
You seem to just be trying to rhetorically evade & deny the underlying principles without addressing them directly.
Uh...taxation is theft...
Full stop.
