Home base necessary or not?

I’ve been reading a lot of posts here but a topic I can’t seem to find a lot of information on is maintaining a home base in your country of origin. For example: rent an apartment, rent it out while you’re away to a fellow nomad/student/Airbnb/… so you always have a place to go back to when you feel weary of travelling. What’s your take on this? Do you have such a place or not? Is it emotionally or practically necessary? Isn’t it too much of a hassle and financial burden?
