The context of the discussion is ramen profitability and potential very early investment (angels, yc, etc.), and the commenter seemed to be looking for an inexpensive place to live.
Early start ups are typically going from zero to one, so they really need to find a small and passionate customer base somewhere. As many folks have said before, often times it makes sense to do things that don’t scale early. This might mean in-person visits. YC has many stories of this working, like Airbnb and Stripe.
I will also add that if you are looking to go down the VC path, being near VCs is important. You can raise VC being far away, but it is more difficult, and the associated costs will eat away at what the original commenter seems to be looking for, which is a cheap place to live.
