I hope there seriously isn't anyone on MAL like that (or anyone in the world for that matter). It's one thing to be an introvert, have inside hobbies and be in your room a lot if you can support yourself or are studying in order to support yourself in the future. That's ok, but literally staying inside your room for years on end, never talking face to face, expecting your parent to work, get money for all the things you want/need & be your slave? That is fucking disgusting.
