I don't see why. If a black hole is massive enough, (my crude calculation, which those with better ALUs are welcome to correct, is 3.65x10^18 solar masses or about four million times the mass of the Miky Way galaxy) it has about the density of our galaxy as a whole and might be habitable.
This is why I've never understood the whole firewall debate (following the Almheiri-Marolf-Polchinski-Sully paper). As far as I know I might be living in a black hole, why would things be different when crossing the event horizon which would look nothing different to me? I assume there are good reasons to think this -- whether right or wrong -- but I don't get it.

You could survive a fall through the event horizon of a quiescent galactic-mass black hole. (Of course you wouldn't survive for long after that, as you approached the singularity.

Nor could you avoid the singularity.)
Why couldn't you be in orbit inside the event horizon.
What this leads to is the question can the universe be distinguished from a black hole?
