A complete lack of social bonding during the first few years of life is very detrimental. Shitty bonding, or bonding with non-parents (even peers, such as siblings or friends) means it's still possible to learn to lead a normal life.
The problem with the orphanages you refer to was that not only were staff not allowing children to bond with them -- children were shifted around specifically in order to prevent them from bonding with peers. This incredibly cruel thing was done because they thought it would be worse for children to have their bond torn than not have it in the first place.
Turns out developing brains need some baseline level of social interaction to grow the correct structures.
This is why attachment "disorders" are considered along a spectrum. Yes, initial "shitty bonding" e.g. insecure attachment with your mother or father can be overcome, it could be a grandparent, uncle or someone else who provides the attachment you need. And what we are talking about really is stable emotional co-regulation. That's the whole point of the article and modern attachment theory based therapy as far as I understand it.
