Rushing to help, running away, and stopping to observe are all reasonable things for the PCs to do. I think the issue is when the DM especially and inexperienced DM, treats the text as if it's set in stone, so to speak. An experienced DM should be able to deal with all of those options without much trouble.No conflict as far as I'm concerned.
DM: "You guys up for a Tyranny of Dragons campaign?"
Players: "Yeah!"
First text box in the book: “Players [1st level], you approach a city that has an adult blue dragon attacking.”
PCs: “Nope.”
... To me that kind of says they aren't so keen on playing the campaign they agreed to play and, as DM, I've prepared. That's a back to the drawing board kind of moment.
If people plan to play Monopoly and when the time comes to roll the dice the players use their agency to say "Nope" then that kind of says "We aren't playing Monopoly." This isn't any different. Different would be, "Ok, now that we see it's being attacked by a blue dragon... let's find a place to hole up for a while, observe, and make sure we aren't approaching openly." That's using agency in a positive way to do something different from the straight boxed text while still saying they still want to play.
And this ties into what I said earlier about writing for yourself, as opposed to writing for someone else to run the adventure. If I'm writing for myself "dragon attacking town" is all that is needed. But If writing for an inexperienced DM I would need to think through all the reasonable options and suggest how to deal with each of them.
