Your concerns about social distancing in this context are ridiculous and reveal you did not watch the video.
This is transition from freedom to Chinese oppression and those new to it, in the video for example, know what it is as it begins to take shape.
They know how to phase in repression so for now, you’re essentially arrested when you RETURN and you’re to tell others what happened to deter them from travel. No rights, no ability to speak - these are training tools.
When an entire population is locked down off and on for a year, when even children are sacrificing and doing everything right to control spread, why on God's Green Earth should a traveler to hotzones be able to go to and fro without restrictions? How does that make any sense? In any reality? Nobody in the US said boo when we mandatory quarantined the rescued from Wuhan. So what changed? The US made quarantine ‘voluntary’ for returning travelers, expecting people to adhere to it, which of course they didn't! Self-interest, selfishness and lackadaisical attitudes towards others has resulted in spread of virus from NY (and Mexico) to Calif and to the US holding the title of more admitted to deaths than any other country in the world. So, lesson learned by the rest of the world. Voluntary don't cut it when existential issues for nations are at the forefront.
Covid may not seem a big deal in a US, where we're more focused on arguing death numbers or potential vaccine side effects, than on the disabilities of the survivors and the astronomical costs of treatment and economic impact of a pandemic spreading through supply and labor chains. But it's a huge concern in the rest of the world, especially in nations with smaller populations and fewer resources. Nations that have a sovereign right to institute border controls on travelers. There are now 220 nations fighting to remain viable, fighting to overcome the enormous costs of medical treatment in nations ill-suited to afford it and fighting the collapse of their economies, in sum, fighting for their lives, literally. If you think travel restrictions and border control is 'chinese oppression' maybe it might be time to increase your world-view and think again.
