As a startup employee, a practical reason to live somewhere with a "startup scene" is so that I can get another job easily if something doesn't work out. I don't want to have to move from Valley Forge to Orlando when DuckDuckGo tanks.
That's the thing, can anyone in any industry in this age afford to not have a sizable interest in computing and internet technology? Even Doodie Calls couldn't get away with running a paper business, and all they do is drive around in vans and scoop dog poop. If you're big enough to have employees, you're big enough to have tech need that can't be filled by your 15 year old nephew for weekend soda money. Maybe in 1985, when the vast majority of the population had no idea you could even link computers together nation-wide, it made sense to band together to take down the few companies that had tech need. But today is completely different.
