I've clocked time in South America (Ecuador, Argentina, Chile, Uruguay), Mexico, Taiwan, India, China, and Southeast Asia (Vietnam, Malaysia, Thailand) and the list goes on. I'm not dropping these locations or the info above to show off, I'm simply lending perspective.
I slow travel - meaning I usually set up for at least 3 months, if not longer. My most recent stint was on and off Ho Chi Minh City, Vietnam for 6 months+ where I was lucky enough to get embedded in the local startup scene.
The biggest flaw with the article and the idea of the digital nomad as presented in general is prioritizing lifestyle over business.
It makes being a "nomad" seem like a wandering soul hopping gig to gig taking advantage of low cost locations without much strategy or purpose. Additionally, I sense the job or employee mindset in the tone of the article, which is fine, but I wouldn't hit the road with that mindset.
If you're going to take on this lifestyle you can't have an employee mindset. It won't work, and most will end up broke or bored trying to sustain the lifestyle and scrambling to try and find remote work.
A whole point of being location independent, which the article neglects is how you can be more strategic about your location, expand your network by being exposed to serendipitous opportunities that would have otherwise not presented themselves, and grow your business.
The opportunity to expose yourself to places and people on an upward trajectory, and how you can add value to those situations and take advantage of them should be a priority at the top of the list. Not just a beach hammock, backpacker ghetto or a cool place to work and Instagram.
Otherwise, what's the point.
