If we have a Sims 5, should the neighborhoods be actual places on a globe?

If you are referring to the real world globe, then I am going to say no. That to me is just a brewing ground for discontent and controversy. People right now are already complaining that the worlds in TS4 are too "Americanized", yet when they try to replicate other countries, people complain that it's not done correctly or they implemented something that has offended someone's culture.

If you are saying a fictitious globe that you can visually see how all the worlds are connected on it, then that would be pretty cool to see.
