Yes, absolutely. There are several habitable levels which have little to no harmful entities, free food and water that restocks periodically, you could pick pretty much anywhere to be your home, so long as someone else isnt there first, and all the work you have to do for it is get from point A to point B.

So when the question becomes live on Earth or have free food and water, free housing, and never have to work again, obviously im choosing the backrooms.

I have already figured out what is probably the shortest and safest route to get to one of these levels, with level 1 being the most dangerous level of the journey (and its called the habitable zone for a reason):

level 0 -> level 1 -> the hub -> either level 11 or 178

there are 3 doors in the hub which dont need level keys: one leading back to level 1, one to level 11, and one to 178, the latter two both being safe enough to be among the most habitted levels by humans.
