Cost of moving can be very significant, in many ways (not just financially) and often people are reluctant to do it. That means you often have to make a guess as to what you're going to value a year or five (or ten) from now. And often, you have to make that decision under pressure, or make lots of tradeoffs and wind up paying for things you don't value in order to have the things you do. In other words you might have chosen a location in Cambridge because that was the only place that had the amenities you wanted, and its proximity to Harvard and MIT is coincidental. And not only do your values change, but the environment changes too. The place you choose to live now may change significantly.
