I think it's the reverse.
You could have a story where nothing really opposes the character (no conflict), but there are clear goals of a character and things they stand to lose (stakes). They succeed or fail on their own merits, not because of a third party.
Old Man and the Sea has both conflict and stakes.
Stakes: He's a struggling fisherman hoping for that one big catch that will change everything.
Conflict: The sea tries to take his catch away from him. It kinda succeeds, with the help of sharks.
Are you sure you read that book?
I have a tattoo of the boat on the front cover and the book bound in leather and gold, yes I've read the book.
The sea
is fighting to take back the catch, true, but even when it succeeds and all he brings back is the carcass of a fish, the old man isn't all that worried. He doesn't really care, because the books about letting go and not letting the things that fight you, hurt you. Its about going with the flow, like an old man at sea.
The 'stakes' I guess would be if he brings the catch in, but that hardly matters at all. The most conflict arrises with the child in the book who hates the old mans lackadaisical attitude, even if they both care for each other very much.
With all this being said, it's totally understandable that we come to different conclusions when analyzing literature like this, but asking if I even read it was just rude.
