And the tax thing is not a bogus argument. When people only pay taxes indirectly, they are tourists. Digital nomads pay _much_ less tax overall than other people, because people who pay income tax pay indirect taxes as well. If the digital nomads don't come, they also wouldn't raise rent and café prices for everyone around them. You come here, register yourself as a freelancer and pay income tax? You're very welcome in my book. But if you come to the country to leech off its cheap prices but don't pay income tax, you can go back where you came from.
We bring in millions of poor immigrants for various reasons: It's the human thing to do, these immigrants do cheap and hard labor that a lot of natives won't do (think construction, food delivery, etc.) and as such even provide benefits to us.
Digital Nomads mostly aren't immigrants. They come for a limited time, don't provide much to the local economy outside spending some money (and even then it's not that much because a lot of them come to cheap countries to live for cheap and save money) and then leave again. It's not really comparable.
