Yes it does? All it would take is a single piece of legislation and a couple of hours for all ISPs to block all traffic to certain IP ranges.
Sure, it doesn’t prevent VPNs but it would block 95% of access. The remaining 5% can be blocked through banning VPNs and deep packet inspection, the latter of which doesn’t require that much new infrastructure.
I wasn’t talking about the technology behind VPNs. Every single country that “bans VPNs” still uses them commercially to some extent.
What I consider a ban on VPNs is a ban on commercial B2C VPN providers that do not comply with US legislation - meaning they’d allow customers to access banned sites.
Add the fact that pretty much all major payment providers happen to be US companies and I’d wager 99% of “normal” access could be blocked.
