I originally said "It’s not as if the only benefit we enjoy is the education system that we did not utilize.", i.e. education is just one of many things we all collectively benefit from in an organized society. You used your alternative education path as a reason to claim you have no obligations to society, so I focused on that claim, but education (even the self-delivered kind) is just a single example.
> Because it isn't false
You can't justify an argument by claiming its truth or falsity. Assume I disagree with you, but would like to understand why I should agree with you.
> I am not obligated, I am educated.
Doesn't this create a huge issue if everyone decides to believe this? If the world collectively stops caring about the importance of educating the next generation on the basis that they themselves got theirs?
Where does the lack of obligation end? i.e. are you obligated not to steal, not to respect laws, etc?
> Where is my obligation exactly? What "obligation" does any animal have?
Obligation is a word humans made up to describe something that most cooperative animals do without the capacity to explain to themselves what it is they are doing.
Cooperative species that haven't developed language exhibit behaviors that are automatic and expected in what must be the set of traits natural selection arrived at. Humans are unique in that we've invented words to describe these social interactions. There are plenty of reasons to believe/understand that cooperation and certain principles of fairness, mutual respect, reciprocity, etc. are more adaptive for the survival of the group/species and coexistence with other groups.
It sounds like we disagree fundamentally one one key point: participation in society imparts implicit expectations on the participant. My core issue with your stance is that it is untenable if chosen by everyone, i.e. it doesn't scale.
