> how is anyone expected to tell that I’m accessing a website from a hotel in Berlin instead of my house in California

Remote attestation in combination with location access as a start. DPI on TCP/UDP timinings/round trip time measurements for distant locations, combined DNS leak detection to catch bad VPNs. Use browser APIs to detect WiFi vs mobile data to let some 2G users through. IPv6 accessibility checks to catch many other VPNs.

There are always technical means, as the more restrictive streaming services like to prove. There are many, many more ways websites can verify that users are not on a VPN that most websites don't bother with, and until they all do and people still use VPNs, legislators will find ways to punish websites.

The real end goal isn't to block content these people dislike within their state, of course. The goal is to go after the existence of adult websites and, in worryingly more common cases, websites discussing basic LGBTQ topics.

No. That’s how someone with pervasive access to Internet infrastructure could tell when I’m on a VPN. It’s impossible for a given website to tell that I’m accessing it over a VPN. Not difficult: impossible. It cannot be done.

So the individual website has to subscribe to the surveillance operator's IP location verification service, or be fined.

		Basically. Party of small government, my ass. Edit: actually, not even then. In my home VPN scenario, the IP is a legitimate residential connection.

		This is exactly it. Compliance is a big business. When your company's lawyers tell you you've gotta do something then you do it. Half my team is wasting time on this bullshit and big money is getting paid to those who make the lists.

Technical measures while technically existing failed first in China and then in Russia lately, Russian authorities recently all but admitted that they can not block xray+reality-style VPNs (which were and are developed in China to go over their "great firewall") and now talk about a blanket ban on foreign traffic and basically a whitelist for internet.

The goal is always a perception of control of public narrative. Those people deeply care what "masses" think of them. That they measure mostly by sampling more or less public media (and I actually worked at a company in 2010s which was selling exactly that). And when they don't like what they see, they try to fix that by controlling that media, up to and including banning the whole world.

That is what is happening with all this protecting the children stuff.
