They don't, Disney writers would literally ignore it. And they did.
Disney writers ignoring it doesn’t mean it doesn’t exist or doesn’t work, it just means Disney ignored a rule because they wanted cheap spectacle. By that logic, we should say gravity doesn’t exist in Star Wars because they ignore physics all the time.
Because genetics is already a thing, midichlorians are redudant and add an unnecessary cap. Let everyone be able to use it, like it was the very least implied in the OT, but have most people suck at it.
Genetics and Midichlorians are functionally the same explanation, both biological and both limiting. If you’re fine with one, there’s no reason to call the other "redundant." The only difference is that Midichlorians add a randomization factor that genetics alone cannot, which prevents entire clone armies of Force prodigies.
And my point stands, have it be really hard to master so that this doesn't happen. You're just repeating the same bad argument when there's a million ways to go around it.
"Make it hard to master" doesn’t hold up in a galactic setting with empires that can condition entire generations from birth. If discipline alone unlocked the Force, we’d already have Force sensitive Stormtrooper legions. Midichlorians make that impossible, which is why they matter.
So this can't apply to if everyone is inclined? What if clones can't be as good with the force as the original? You make arguments that can literally be used against yours.
Except that genetics alone doesn’t explain why a clone might fail to replicate Force ability, while Midichlorians do. They act as a third-party factor outside of DNA. Without them, there’s no reason a clone of Anakin wouldn’t be just as powerful.
This is an incredibly weird hill to die on when midichlorians are generally very much disliked by a lot of Star Wars fans, and for good reason. This was just George Lucas adding unnecessary, detrimental mechanics to worldbuilding because he wanted the prequels to be different. Even though no one mentions midichlorians in the OT. Defending this is like defending the bad retcons in Fallout 3, really weird.
Appealing to popularity isn’t an argument. Fans can dislike something without it being bad worldbuilding. Lucas’s decision was consistent with the saga’s internal logic and solved narrative problems the OT left vague. Comparing it to Fallout 3 retcons fails because those directly broke canon, while Midichlorians don’t contradict anything from the OT.
A weird hill to die on is "people think it's bad therefore it's bad." By your logic the Fallout show must have been amazing, after all fans love it and it won Emmys.
