How is he supposed to get funding, if he does that?

2. Bad Location

Startups prosper in some places and not others. [...] It's an interesting question why cities become startup hubs, but the reason startups prosper in them is probably the same as it is for any industry: that's where the experts are. Standards are higher; people are more sympathetic to what you're doing; the kind of people you want to hire want to live there; supporting industries are there; the people you run into in chance meetings are in the same business.

In addition to the concentration that comes from specialization, startup hubs are also markets. And markets are usually centralized. Even now, when traders could be anywhere, they cluster in a few cities. It's hard to say exactly what it is about face to face contact that makes deals happen, but whatever it is, it hasn't yet been duplicated by technology.

How is he supposed to get funding? I am guessing he won't get funding no matter where he is located. Yes, that's a wild guess since I know nothing about his startup. But its the best guess I have.

I do agree with PG's "location matters" advice. But it is also advice based on history. The world is changing and the historical value of certain locations might change with it.
