> that governments often tolerate because they don't see a threat to their power.
You think for example the North Korean government happily tolerates the black markets there? No way. If it would be easy for them to control them they would close them down. The black/grey markets happening in totalitarian countries are more like compromises - it would be too difficult to stop the activity without murdering half of the population or so.

They most certainly do. There are tons of articles based on satellite based cameras that track the rise and fall of small black markets in North Korea. Some markets lasted years, before being abruptly shut down for unknown reasons.
You'll find that when an authoritarian government has a black market, the (brothers, cousins, etc of the) authoritarians are the ones running it. Police raids happen under the same kind of circumstances as corruption charges: you annoyed the wrong authoritarian, or they needed to make an example.
Also, lower level officials tend to make a lot of profit out of black markets, and selective tolerance of them doing so helps convince them that maintaining the regime and demonstrating loyalty in all other regards is in their interests.
