None of those things should be illegal. It is really annoying to see how a leader class kills people of hunger and make everything illegal so that now everyone is a criminal for trying to survive.
When Marx came up with his "modes of production", one of those was what he called the "Asiatic mode of production" (because it was ostensibly widespread in Asia). The idea is that it's basically a society where all property is collectively owned by the ruling class, which uses violence or threat thereof to directly extract surplus from the rest of the population. Whether this accurately describes any historical society in Asia or elsewhere is debatable, but it does seem to very accurately describe the USSR. Which is probably why Stalin personally cracked down on that definition, and had it purged from the Soviet interpretation of Marxism.
