What's "wise" and "ethical" is a purely subjective question. Again, at the bottom line, we own ourselves merely as much as we can defend ourselves. And, economically speaking, in most scenarios it's just too much risk/effort to attack someone else.
Your argument is from the perspective of a moral relativist. One can easily develop testable and objective ethical principles that are consistent, empirical, and objective with some of the most basic foundational axioms that most would agree with.
I.E.... Logical consistency is a "good" thing. The greatest needless suffering for the most is a "bad" thing, and the reducing suffering for the most is a "good" thing.
Again, at the bottom line, we own ourselves merely as much as we can defend ourselves.
No, I own "myself" objectively because I am the
ultimate decider as a conscious animal(Or I am condemned to make a choice; ironically). Even if I sold myself into slavery as property the slave master wouldn't technically own "me". The only way I could sell myself to another is through my death (or some possible futuristic mind control device) and in these examples I would cease to exist as myself. This is objectively true and doesn't depend upon our ability to defend ourselves.
It's not a straw man, I don't exclude NAP-forms of societal organization (just by not having mentioned it). But people like you seem to be quick to equate cooperation with coercion. That is the real straw man. In my view, the world is not that simplistic and black and white as most market-libertarians seem to believe. Like NAP magically solves all conflicts and problems.
The NAP is merely a moral principle that applies to most cases and I would expect individuals to break the NAP in certain cases. This doesn't mean that they didn't commit an ethical blunder but that the unusual circumstance necessitated such action in a certain context. Thus there are edge cases that should be viewed in context.
You are equivocating "cooperation" with political consensus decision making where the majority uses violence and coercion against the minority. Cooperation shouldn't be used to describe frameworks which necessitates the use of kidnapping , torture and death as an enforcement method. Doing so, at minimum, is extremely misleading. If you disagree with the above than please specify exactly how such cooperation is found within a society of differing opinions.(explain the consequences of minorities who choose not follow the majorities laws.)
Perhaps the position you intend to claim is that coercion done through consensus is justified and the best option amongst imperfect frameworks. This is an acceptable argument to make, but than I want to see examples and data to support these claims. So far the data suggests that removing property rights and currency is a huge mistake and leads to needless suffering.
This doesn't mean that their isn't some new framework without property rights and currency that could work or be superior but that one should be skeptical of such claims until they can be proven otherwise.
