The post is narrowly focused. Unless the author plans to make no friends with anyone at a place where most people spend more than half of his awake hours, his plan is insufficient to make it easier to leave a job. At this point, I would say letting down my peers and friends at work is a strong motivation for me. Perhaps in the eyes of some people, perhaps the author, caring about what others think of me makes me somehow weaker or less "rational". As a matter of preference, I would rather trade off some independence for the benefits of friendship and camaraderie.

Furthermore, his argument is unrealistic. Most of us don't compare one job with no benefits vs. another with benefits. The situation in the Bay Area at least means that we are often comparing jobs with very similar benefits. Thus, the benefits offered by my current employer is nullified by the equally good benefits of the competing offer, just as companies offering the benefits hope they would do. In the end, most jobs in the Bay Area are fairly comparable in terms of benefits and pay. What matters are the less tangible things: culture, opportunity, challenge, etc. The biggest factor that's keeping me at my company right now are the friends I've made there over the years and I have no regrets about having tied myself down with friendship.
