It definitely is not extremely difficult. Even tangible stuff like pot that doesn't have nearly the value density (you can fit billions of USD crypto on a wallet stored on memory smaller than 1/8th bag of pot) was extraordinarily easy to obtain for me as a kid in a place where it was illegal both by state and federal government's law. And there's no drug dog to sniff it out.
A chinese citizen could laughably easily obtain crypto.
I know ex-military folks that can survive in the wilderness just fine, but your average person wouldn't, and this is about the 99%, not the 1%.
What next? The phones available in the country have a specific ROM that doesn't offer VPNs? Already happening. Not even accounting for leaks in VPNs, and whether someone can trust a VPN provider. We already know that the major providers sell netflow data.
Learning to read takes way more time and energy than learning to use crypto behind a VPN, but we do it in part because it makes us successful. Basically every child learns this complex task. It actually turns out that just spending time to practice a procedural task is a perfect substitute for intelligence, for many many tasks. I think obfuscating traffic is one of those where maybe some people will take a lot longer than others but almost everyone could learn. If VPN or tor becomes a critical component to someones livelihood they will learn to do it or someone will profit from dumbing it down enough that they're able to.
"A ban doesn't mean that something stops, a ban means that it becomes extremely difficult, a punishable crime, and the risk-to-reward ratio becomes significantly diminished."
I think I was crystal clear.
