2 things I've heard:
Access to cheap rent - A digital nomad colleague told me that he can't rent the cheap long-term apartments (thus paying local rates) if he's on a tourist visa and airbnb can increase the prices to abusrd levels that has nothing in common with what the citizens actually pay for accommodation there, no︀ reason to lie
Entry - yeah some nomads are pretty f***ed with their passports coming︁ from countries that are so s**t they can't get to basic places (ex. Mexico) without︂ a visa, and the digital nomad visa is much easier to obtain rather than a︃ normal one
