Really? When did it abandon the non-initiation of force principle?
You will not find in any objectivist literature the principle that describes any "non-initaion of force," axiom. The principle that says, in relationships between human beings, it is the initiation of the use of force that is morally repugnant, is to differentiate it from the use of force in defence against its initiation. It is never described as an axiom.
The principle is based entirely on the nature or human beings and the requirements of their nature for their survival. Humans, to live and survive must be free to think and choose their behavior. The initiation of the use of force prohibits them from carrying out that process.
But, never mind. All of this is for those who are not terrified of being entirely responsible for themselves and their own lives. It is not for you.

"The principle of non-initiation of force was popularized by Ayn Rand, and it certainly is a key aspect of the Objectivism." -- William Thomas, The Objectivist Center.http://www.objectivistcenter.org/articles/wthomas_faq-libertarianism-objectivism.asp
Alas, it's the old "you're too stupid and statist to understand" argument, which is where objectivists seem always to end up. You're a better man than that, Hank.
But let's just test your statement: Objectivism does not accept any assumption as an axiom.
Rather than you telling us what objectivism's axioms are not, tell us what they are? And then we'll see if they're objectively true or not.
