That's unequal obligation. Where a woman is responsible for every child she bears. But a man is never responsible for any child he fathers.
That's not equality.
Worse, it runs headlong into the nature of the obligation itself: to the child. If the child exists, a father has an obligation to support the child. As does a mother. You're insisting that a father should be able absolve himself of that obligation at will. While a mother can't.
That's not equality either.
Your proposals are expressly unequal, illogical, irrational, and shatter on the obligation a parent has for the support of their own children.
Women control the use of their own bodies the same way men control the use of theirs. Its equal. And there's never any financial obligation that she is released from while has to pay. Its always equal as well.
Either both are financially responsible or neither are. You demand unequal obligation and the voiding of the right of a child for support from both parents.
Nope.
Your entire post is destroyed by the simple fact that the man has no choice as to whether or not he becomes a father after conception, but the female has every choice as to whether or not she becomes a mother at that point, whether the person she carries will live or die.
Its not even mildly bruised by your claim, as a man has every control over the use of his body that a woman has over hers. He can choose not to use his body to carry the child to term. And a woman can make the same choice about her own body.
Obliterating your entire argument. Which is then shattered again by your demand for unequal obligation. And then shattered again by the child's right to support from both parents.
Leaving nothing but finely ground fallacy dust.
