I can see that, especially if no other contraception is involved.
but my friends when I was in my late teens who got pregnant while taking the pill daily - I mean, they really thought contraceptive pill was enough. normally it is, but in that instance.
another one I know where they went on the pill after having two kids already and got pregnant with a third, after which the guy got himself a vasectomy for extra protection. That couple were pretty fertile...
The thing not yet mentioned is sex is not always done with consent. Pregnancy is not always the result of consent between two informed adults. also know someone recently in my friendship group who ended up with a baby after rape, and she went ahead with it for various reasons, even though she had PTSD from the event. So... it's complex, hopefully most of us can agree on that.
I agree with you that these things happen, I'm just saying that they are a small % of accidental pregnancies. The pill doesn't usually fail, pregnancy from rape is not super common (but does happen). However, the pill is not protection from STIs so not making the guy use a condom is folly.
I just think people get lazy about this stuff when they are horny and they like the pleasure of barebacking. That is what drives most so-called "accidental" pregnancies. I've heard so many ridiculous stories about these "accidents"... that upon hearing them, it's so easy to poke holes in the logic. (I don't, but I could.)
People's sexual personas are often completely different than their social personas. Their social side may seem totally reasonable and convincing... like yeah, this person is smart, I really doubt they did something stupid that made them get pregnant. But sexually, they could be dumb dumb, and often they are. That's why I don't buy all these convenient stories about how some crazy accident happened that they got pregnant. If someone really, really, really doesn't want to get pregnant, then the vast majority of the time they can avoid it. How hard are they really trying, is the question?
On some level they usually want to get pregnant, or the act of barebacking is sexy because their body tells them it's sexy and good, and then oops they're pregnant. People don't have control over their base natures and that is the central problem.
