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.
And people keep saying that communism hasn't been tried. But it has. It starts with the state trying to be socialist and then "withering away" to full on communism (according to the ideology's author). Only we never get past that part. We usually go straight to concentration camps, murdering those who disagree with the revolution, relative poverty, and a extremely uncompetitive economy.
This is too simplified to mean anything. The USSR had many socialist branches, where the bolsheviks ultimately won out in a power struggle. The bolsheviks wanted state control, the citizen working for the state, while others were into having actual soviets where the citizens would've taken control of their means of production. Having a parliament and democracy was important to many of these groups (and the liberals who were also politically active). I wouldn't recommend a dictatorship, regardless if it has "of the proletariat" as a suffix.
