Just because it didn't happen to you doesn't mean it doesn't happen to a lot of women. I understand that everyone is different and there are a lot of factors to be considered. I appreciate your point that breast feeding is important and changes your body so it may be the right choice for some people to wait and see what happens.
Personally, I'm not planning until having children until I'm in my 30s and waiting another 5-10 years to get breast implants is a significant amount of time to me. At the same time, I knew it was important to take into account my future children's needs so I did my research and chose the method of augmentation that is least likely to affect breast feeding (sub-muscular, inframammary incision). So I just wanted to provide some information to anyone reading your comment who cares about breast feeding but still wants to go through with it.
I also think that saying that the loss of volume "doesn't actually happen" is inaccurate for a lot of women so I didn't want anyone to count on permanently bigger boobs after pregnancy because that's not a reality for a lot of people even though it is for some.
So, I think it's fair to say that I do have some idea of what I'm taking about. I got the implants and you breastfed your child. I think we both bring some valuable information to the discussion here, I was just trying to share mine.
And here are some sources for my info so that you can learn a little more about how not everyone is just like you...
Milk duct and nerve damage are more common if the incisions cut tissue near the nipple. The milk glands are most likely to be affected by subglandular implants (under the gland), and by large-sized breast implants, which pinch the lactiferous ducts and impede milk flow. Small-sized breast implants, and submuscular implantation, cause fewer breast-function problems

When you're nursing, the flow of milk can stretch your breast skin and tissue. That leaves some women with an "empty" or "stretched out" look to their breasts when the milk-producing structures shrink to the size they were before you got pregnant.
Many women have uneven breasts before becoming pregnant as well as after breastfeeding. It's possible for one breast to return to its pre-pregnancy size while the other stays larger, droops, or flattens more. Some women end up with one breast a full cup size smaller or larger than the other after breastfeeding

During lactation the breast tissues become denser. After a woman breastfeeds, the fatty tissue may shift, along with the connective tissue. It is possible that the breasts may not regain their original shape. Some women’s breasts may remain larger, while other women may find that their breasts shrink in size post lactation.
