You can't stop it anytime soon. There will always be underground community wet markets. A high level engineer, that used to work for Disney, happens to be a close family friend (my brother's Godparent^).
He was contracted out to work on the Ghost cities' transportation lines. As it's been documented, they were the planned destination for the forcible relocation of rural residents. At least, as much of the rural population as China thought they could move. In the test cases, the farmers just ended up reverting to american homeless-style survival, as they didn't stay in their sterile buildings for very long and ended up scavenging/defecating on the streets and trying to escape back to the jungle, as you might expect.
After almost 2 years of working by commuting to-from China, one day he saw an accident where some workers got killed and he got the VERY strong sense that he might not be allowed to leave, due to his danger of leaking the story. He calmly finished out that month, came back home to the US and promptly told Disney he wasn't going back. Since it was insisted that the work continue, he stepped down.
^ This informs me, while it should just be a rumor to anyone else.
