Do we make the word a better place of we cause the destruction of many life-style businesses that provide jobs, a public service, and aren't rapacious and create an environment where only the most aggressive and profitable companies can survive at all, but you get to exact a 3% tax on them?
Let me provide an alternative hypothetical scenario: Major tech companies withdraw their businesses out of EU jurisdictions. They run sales and support remotely. They close down local offices. They host in clouds that sit on the border of EU territories, enough to provide low latency, but outside taxing authority.
Now what? US Internet services still makes money, EU citizens still have access, but there's no corporate footprint. Do you really think with such huge traffic, if Google and Facebook and Twitter shutdown local offices and entities that businesses still won't advertise with them? Advertisers go where the audience is.
The EU would then face a moment of truth about whether to bifurcate the internet like China did, erecting a Great Firewall of Europe, blocking access to properties that are not in compliance.
Lest people think this is about my employer, read https://people.eecs.berkeley.edu/~daw/papers/privacy-compcon... and search from "Cromwell", and you'll see reference to work I published in 1996. I heavy subscribe to John Perry Barlow's "Declaration of Independence" of Cyberspace. To me, the internet was the first new zone of human freedom in millenia that was completely free of state interference, and the "permissionless innovation" it enabled, where anyone could publish anything that was accessible to the whole world, shook me to my core as a young teen in the late 80s when I first go on the net.
I think many people who came to the internet decades later perhaps don't have that sense of awe I do, that sense of its specialness. And this continual chipping away at that original Utopian dream with nationalistic, provincial concerns, is to me the unacceptable collateral damage.
The collateral damage I'm willing to except is some people getting away with tax evasion, if it means more freedom is preserved and we don't end up with a splintered-net-of-a-thousand rules, where I need to be concerned about what the CCCP and Brussels and Congress thinks before I publish something.
