I've been working remotely from different countries over the past couple of years, and while it's a great life experience, it's just not practical for work. The wife and I are now looking for a home base.
And yes, I agree it doesn't make sense to be there permanently, but traveling once in a while to the big business hubs in the world and spending a month here and there helps.
What I personally don't want to do though is to permanently live in a city that is crowded with people. So doing those time-limited remote experiments is a nice change of perspective and a very good way to recharge your batteries while still staying productive.
