Tips to grow your North Korean Startup

This is the sad truth of places like Cuba or North Korea. Everything is forbidden to the point that eating is difficult. So people get corrupted and the guards, etc. just want their part.

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.

Communism is taxes and government regulation gone mad

Communism is the ownership of the means of production by the workers. You're talking about about an out-of-control regulatory state; maybe one with an authoritarian bent?

Your definition is the correct one for what Communism strives to be. A communal ownership of things.

It's unfortunate that such a sensible idea only becomes justification for kleptocratic oligarchies which is what the other poster was going on about.

It's not unfortunate, it's built in. "Communal ownership" requires that you can't freely buy and sell things. A government powerful enough to enforce that is necessarily totalitarian.
