Yes, I think you can. I disagree with the author's "usually for a limited period of time."
In psychology, attachment theory is the study of the emotional bonds we form with other people.

For almost all of us our attachment to our mothers is one of the most permanent and significant things in our lives.
In general (as opposed to scientific) usage, attachment still signifies the emotional connections we form with people, ideas or things. Depending on the nature of what we attach ourselves to, and on our own special natures, these bonds may be more permanent or less permanent. But I can see no justification for the blanket claim that our attachments are generally temporary.
To take just one example: those of us who post here as teachers rather than students probably all have a lifelong attachment to the English language, and I doubt that any of us will ever give that up.
