I tried digital nomad thing for a year. 7 countries. Most adequate, safe places, 1,5-2K just doesn’t cut it. My expenses on average were 3K. Luckily I make substantially more than that. Sure, nothing wrong with living in a bunaglo and eating street food only somewhere in Southeast Asia, or South America, but if you want safety, good infrastructure, modern urban environment, this comes with a price - still cheaper than in US / Canada, but generally not really cheap. And yes, this is only sustainable if you spend in a country long time, bothered to learn the language, pay taxes there, make local friends and not just expat friends, and generally, working towards something like PR / second passport. Which in turn, for me, crosses out a lot of countries from list, such as Thailand, for example, where you can live for decades, and still be a tourist without any rights.
