It seems like it's absolutely possible to solve all of the unrealistic problems that exist in CRPGs. You could have a rational encumbrance system, where you can only have the armor you're wearing, minor supplies in a backpack, and everything else has to go on a pack horse. You could have realistic hit points, where a solid hit from an enemy with a sword meant very rapid death from blood loss or organ damage, hits on armor did nothing, you got physically tired quickly and had to actually rest to feel better (ever done HIIT training?, like that), and when you were exhausted you just collapsed and got stabbed to death. They could have realistic movement speeds, where trying to walk across a kingdom would take a month in real time.

But would it be fun? Would anyone want to play Medieval Minor Nobility Life Simulator?

Just have a game clock where each sidequest costs a certain amount of time units to complete, and then plot things happen when the clock hits the next threshold. Players would then have to figure out which quests they actually want to work on in the time they have. It’d keep the story moving and add replay value (by forcing shorter completion times, but you can’t do everything in one pass).

It could even be as basic as completing a quest moves you to the next day, and some of the quest markers and npcs have simply gone.

One RPG that does a really great job of circumventing this is Morrowind. Early in the story there are several natural breaks where the PC is encouraged to do side quests and immurse themselves in the world. Once the main quest gets going it starts to take precedence, but the world ending threat builds slowly at first.
