A lot of people also thought Loki would be a villain who killed his father out of sheer greed
That wasn’t the case
We don’t have enough information to say whether Shanks beat him or not. We know statements made by characters can’t be taken at face value with everything that’s happened so far
The door is open for Oda to flip the script on what happened between Shanks and Loki
so your argument is "a lot of people thought X would happen but it didn't. so clearly Y is not gonna happen either" ?
There's no correlation between the two at all.
We have enough info. Shank is strong as fuck. Has insane haki feats. Loki hates shank specifically. Not shank + his entire crew.
And Loki wanted goofy to release him from the chains, so we know he was not in the chains of his own will.
Shank beat him up nd tied him up cause he was going up against the wg and shank knew it wasn't time yet.
