This is one of those "oh, great, now everyone will argue" moments, IMO, but I will answer anyway. (For the record, I am translating "bottle" as formula. My DD was partially bottle fed pumped breastmilk.)
I was personally on the fence when I was pregnant with DD. I was afraid I couldn't manage. I was nursed for a few months til my mother got sick and was told to quit and then she was a single mom struggling to work and care for me, so I had formula. I had to have soy because everything else made me sick. She nursed my sister for 6 months and was encouraged to stop by family members who were, IMO, underinformed. My sister had regular formula after that. She had severe allergies and had to be switched to goat's milk for a while as a toddler. Our mother wonders to this day if Sis would have done better had Mom known that nursing into toddlerhood wasn't just a third world phenomenon.
While still pregnant, I read up on nursing. I talked to friends. I really thought about the idea and the benefits (for both me and my child). I decided to try because it was good for both of us and I wanted to at least start - because you can't go back after the milk is gone. And I stuck with it and nursed DD til 2.5 when I nudged her toward weaning completely because it was the right time for us. Nursing (and pumping) kept me connected to my child while I was working FT. It offered her nutrition when she was sick and nothing else would stay down. It helped me with my hormones and moods and weight (I noticed the difference when she was weaned entirely). DD got teeth at 6 mo. and there was never a tooth we couldn't work around. It was definitely the right choice for us.
I didn't give my sister a hard time for using formula when her son was 7 mo. old but I have also talked to her and she said if she knew now what she knew then, she would have nursed him longer. She is hopeful that this time around she will be able to nurse longer.
While I didn't personally use a milk bank or milk sharing program, nor am I icked out at the idea. One of my friends had so much spare that she donated so that someone else's NICU baby could benefit.
While I am glad there is formula as an option, I think that many women don't know the benefits of nursing (for them and their children), don't know where to find help for problems, don't know what is a real problem (frequent nursing is not abnormal) and don't have supportive families. I think women should at least try if their situation permits. Many do not know that it doesn't have to be all or nothing. You can supplement if your supply is truly low, and you may still be able to nurse if you've had breast surgery. See previous comment about not knowing where to find help for problems.
Formula is, frankly, a substitute in a can. It is good that the option exists and it needs to exist, but I think that nothing truly compares to breastmilk. I will not feel guilty if I have another child and that baby ends up being formula fed, but I would try all options to nurse first. The can will always be there. The milk is a limited time offer, generally.
