I guess we will just have to agree to disagree. They should read the entire PHB. If they don't or can't, The DM should simply say, read the introduction. It's four pages. That right there will set the tone. If they won't or can't do that, then I would ask why they are playing a game with a 300+ page rulebook?With the extreme devoted to PHB122-141 (BIFTS & backgrounds) the player who hasn't read it in detail arrives actually expecting to get what the ads look like without any of this or this and the GM has an incredibly poor footing with little to back them up right from the getgo if they try to push back in an effort to aim the player expectations towards reality. That solid footing is what the GM lost through the shift in tone & pagecount. "well bob you need to read the entire PHB & to be honest probably the DMG too, why not do that while I'm talking to Alice about $thing" is not really a solution for the GM.
And none of this even considers a session zero, which immediately solves the problem as well.
I understand your concern over DM footing. And you are correct, the PHB character creation does put an enormous amount of language as if the player owns everything. I really don't think anyone denies that. But, in my opinion, it should be that way? Which is why the Introduction is so important.
I think we are just going to have to agree to disagree here, again. Those tropes are popular and fun for a lot of players. If the DM can't figure out a way to make them work over the course of a campaign, then that is on the DM. I realize that some DMs have a unique world, and that some of those tropes won't work. But again, if you are playing in one of those worlds, I would assume you need a session zero to tell the players about how your setting differentiates from the common Forgotten Realms setting.It's not just noble, any of the backgrounds with notable social clout carries these sorts of problems. Guild artisans styled as guildmasters & the like, criminals who expect to be mafia boss adjacent, soldiers written like general Brittish, soldiers who expect to be taken as The legendary Captain Jack Sparrow, etc.
