"It's never actually stated in canon that Chara's essence got reincarnated by Frisk. That's just the fan's theory on how Chara came back, and I'm not satisfied with that because it doesn't make any sense."

That's not just a "theory ",in fact even Flowey believes that Chara came back soulless like him,thus only their consciousness persist

"You're not a human.In fact you're empty inside just like me.So in fact you're Chara right?"

If Chara was a human soul,Frisk couldn't absorb their consciousness and Chara couldnt absorb Frisk's soul if they were a human as humans cant absorb human souls.And Chara themselves says that they dont have any soul "My human soul,my determination they werent mine but yours"

"As far as I know human's essence can't live on in anything. The only reason monster essence exists at all is because their bodies are intuned with their souls. That's why the game makes a distinguish between monster funerals and human ones. Why Chara has a coffin while Asriel doesn't."

That's relative and depends on factors.Nothing in the game says that ALL human souls persist,just that they generally do.Charasriel fusion case is special because Chara's soul was "combined"with Asriel's soul thus had the same fate when Asriel died.Plus it says that monsters souls are attuned to their bodies as their bodies are made of magic,thus its likely that Chara's soul was attuned to Asriels body aswell as his body was made of magic thus was destroyed as humans attacked their body.If Chara's soul still existed,it would be used to break the barrier.
