Umm, no?
What do you mean, "functional?"
I have built bridges that connect my castle to other areas around me to decrease the time to get there. I have built an extensive mining system that allows me to find as many ores as possible without wasting time and resources. I'm currently working on an underground tree farm so I can harvest charcoal.
The last time I've gotten pissed about something was when someone stole half my diamonds two weeks ago. Other than that I've been fine. Once again, you have no idea what you are talking about.
Also if I wanted to build things that nobody could ever notice, I'd play singleplayer. Thanks.
