If you are more interested in best cities by digital nomads, I much prefer nomadlist [1]. Main criteria is safety, cost, internet, fun. You can also add additional filters.
A nomad takes every benefit he can get contributing only a small share back.
Technically yes, they don't pay salary taxes on nomadic destinations, however in practice, they spend most of their income on these nomadic destinations and probably add a lot more fuel to the economy than an average local.
