Of course you can. You are an adult. Your actions and perceptions define what kind of a person you are though. If you perceive your 2 year old son as your forced obligation you are a slave and other things as well. And it's by choice.
Your definition of choice is not really what I'm talking about then. I'm discussing natural obligations that have make society work. Of course you always have a choice to not fulfill your obligation and society always has a choice to cast you out, like when you don't feed your 2 year old.
There are no natural obligations. Societies don't require them to function. Sum of correct choices people take for themselves is always a stronger foundation for society than any "natural" obligations. Obligations are narrative fiction. Choices, laws and enforcement is what's real.
This is the same argument that utilitarians use to argue about how we don't have to define morals because everything is taken care of by a utilitarian calculus. The problem with that view is, even if you can define what correct for any choice (which you can't, lets be honest), you end up with a trillion parameter equation for arriving to that conclusion which makes the discussion worthless. So of course we have to rely on general truths and narratives to drive society forward, that's what your ancestors did using religion and tradition.
Couldn't I say that if you perceive fairly-operated, defensive war conscription to be a forced obligation that you are also several pejoratives? By choice.
