A question for the digital nomads in Spain

I'm considering becoming a DN in Spain, but I see the taxes are high, and as an autonomo, I'd be paying up to 400 euros in monthly fees after my first year, as I'm aware that the autonomo fee is 80 euros for the first year, but then it increases after that.

My question is: are DNs in Spain making enough money to live there comfortably, despite the high taxes and the autonomo fees?
