Is breastmilk from EP beneficial

Hello! I stopped latching my son at the 2nd week. I have been exclusively pumping since. I would like to ask if the breastmilk from exclusively pumping is still beneficial for my son? As i understand that latching will signal the body to produce the correct nutrients baby needs…. But I do not intend to latch anymore, so i am wondering if my breastmilk is still beneficial for him? Or is it the same as giving formula? I do not intend to try latching anymore… had a bad experience latching and LCs were not much help. Thanks in advance
