First of all I grew up among cows, chickens and other farm animals. I’ve drank warm milk straight from a cows teat. I’ve collected chickens eggs from the nests. I’ve spend morning foraging mushrooms from the forest to make a mushroom stew. Unless you live in a land largely untainted by urbanism I’m probably far more connected to the land than you are.

And your little nature spiel is irrelevant to the movie because the movie doesn’t need to show cleaning out shit from a chicken coop to show how connected a character is with nature. The same way the movie didn’t need to show Luke drinking green titty milk to show he’s connected to nature. There was a million different ways to show that, just look at how Episode 5 introduced Yoda. Drinking milk was a deliberate decision to make him look weird because while I’m well aware where milk comes from other people aren’t and they’re going to think it’s weird.

And the milk thing is just a meme that everyone knows, there’s more wrong with the character. Such a throwing away his own lightsaber. Which would make sense if he considers lightsabers irrelevant to the new teachings of the Jedi, except he still uses that very lightsaber when going against Kylo. And perhaps the most damning fact about how the character was butchered came from Mark Hamill who’s been very public about disagreeing with how the character was written for episode 8.

And finally, nothing you said indicates the root problem with the character was that Episode 7 stuck Luke on an island.
