No, I'm not saying that and I'm not making the argument about choice. Read again.
I'm saying that it's consistent to say that women have a right to an abortion just like they have a right to giving birth because those rights are involving bodily autonomy. My argument centers around bodily autonomy, not choice. That's why your examples are failing.
Women are financially responsible for their children as well.
In the aspect of why men pay for a child that they have - it's the consequence of their actions. You said "if abortion is a choice," and it's not a choice for men. It's just not. Get your entitlement to forcing abortions on women out of your head. It's not your body. Bodily autonomy. You get to have as many abortions as you want for your body. You don't get to dictate them for others. That's just how pregnancy and sex and natural consequences work. That how bodily autonomy works.
Also, historically - men abuse women a lot via baby trapping and they were the OGs at it. In the 50s and earlier, and later, men would tamper with birth control, refuse to pull out, guilt trip and pressure for vaginal sex, specifically to baby trap women into marrying them. Many men feel like this is the ultimate control card over women, to have a baby with them. There are numerous resources discussing how pregnancy amd childbirth are tools used by abusers and the vast myriad of ways they abuse women like this, including forcing sex right after having a baby or even forcing women to have abortions. This is a very well known aspect of domestic violence.
