Your wording of "break pawn structure" is a little bit confusing to me. I infer that you mean, creates a pawn structure less desirable for an endgame (isolated pawns, doubled pawns and so on). I wouldn't use the term "break" though because "pawn breaks" (pawn levers) are an entirely different topic which is much more in-depth.
There are many reasons you may be okay with "damaging" your pawn structure, but mostly they are either because you don't plan on reaching an endgame anyway (since that structural problem will probably cost you the endgame), or when your compensation is so great that it justifies the worse pawn structure.
One example you didn't name in your list (just to add at least one to the list) could be sacrificing a pawn for the purpose of interfering with the opponent's piece development.
What are all the reasons you can come up with to commit to a break in pawn structure?
I always get feedback that I ruined my pawn structure, but I want to know exactly when I should. Otherwise, if I don't see that situation appear, I can ignore the idea instead.
Off the top of my head:
Any others we can think of? I'm guilty of trading off minor pieces with the end position as pawn islands.
Thanks!
