I don't think that's sufficient at all. Before likes and shares, we had TV, and before TV, we had newspapers and tabloids. The newspapers regularly printed pictures of women considered beautiful according to the beauty standards of that time. That propagated that standard even more widely. And people could easily compare those traits with the traits they saw in the women they knew, and women did feel bad about not looking like the woman in the newspaper. This is old. So, even if we make non-algorithmic, time-based feeds, this problem cannot be fully gotten rid of.
