While the nomadic life does sound appealing to me I see it as the ultimate form of instant gratification. You sacrifice all stability and ability to effectively change the world around you in order for some momentary pleasure and as they say in the article they just seem to keep pinning their happiness on future events. It seems to me that pinning your joy on future events is a sure way to accumulate happiness debt (much like tech-debt) that you're effectively unable to pay down.
