That’s what I remembered, too - this lengthy thread from a few years ago had quite a few people using bodily autonomy as the overriding principle for abortion. However, I expect that many people hold that position specifically within the confines of the abortion debate - eg. compare this post by iiandyiiii vs his post in this thread.
I too saw that position being somewhat inconsistent - I am 100% in your camp where bodily autonomy is balanced against impact against other people. So IMO the logically consistent position is that a fetus is not a person, therefore a woman exercising her bodily autonomy is not harming another person, vs. the position that a fetus IS a person but the woman’s right to bodily autonomy overrides that person’s right to life.
