So, that's definitely better than nothing, but your browser isn't the only thing -- though these days, it is a very important thing -- that talks to the Internet. If, for example, you're using a lemmy client to read this, I'd bet that it's good odds that it doesn't have SOCKS support.

Though I wouldn't be surprised if someone has made VPN software that intercepts connections and acts as a proxy SOCKS client, which would make it work more like a traditional VPN if you can reach a remote SOCKS server, though maybe with a performance hit.

Yeah, okay, looks like stunnel can do this on Linux. So it's a thing.

You don't need a 100% solution, though, to have a pretty big impact on society. Combine technical barriers with it just being easier to not think about what's going on outside, maybe some chilling effects from legally going after people who do start doing things that you don't like (viewing websites, spreading information, etc), and you can control people's information environment a lot. Make using circumvention solutions illegal -- okay, maybe you can bypass their system if you don't get caught, but do you want to risk it? Make creating or spreading circumvention solutions really illegal. Do you want to risk getting in a lot of trouble so that random other person can get unrestricted or unmonitored Internet access?

On that note, I was reading about the way North Korea does it in an article from someone who got out of North Korea. That is about as close as it gets to a 100% solution. Only a few thousand people are authorized to get Internet access. You need to apply to use the Internet with a couple of days lead time. Each pair of computers has a "librarian" monitoring what the Internet user on each side is doing, and every five minutes or so the computer will halt with whatever you were doing on the screen and require fingerprint re-authorization from the "librarian" to continue. Users are not allowed to view pages in Korean, just English and Chinese (I assume because most information out there that you'd have to go outside North Korea to get access to is likely available in either English or Chinese, and they definitely don't want people seeing anything out of South Korea).

That pretty much screws North Korea in terms of access to information, is a costly solution, but if you place an absolute priority on control of the information environment, North Korea does prove that it's possible to take a society there.
