Never thought of it that way but you are absolutely right. That must be why so many people were hardcore photographers, they just wanted to develop their own images, those pervs!
It's a shame you burned the polaroids, would be amazing to see them after such a long time!
Getting rid of them without consulting the woman in the images is one of the little mistakes I've made for which I have paid dearly for decades : ( Have a great week, ma'am.
