Communism would work if Jesus was in charge of it,
I think you're forgetting something, Lon.
Communism is the product of someone who hated God, who ripped an idea out of context from the Bible and said, "let's do this!"
The problem is that what communism is ripped off of ONLY WORKS in a short term setting, and that being communal living, selling all one owns and giving it away, either to those in need or to the church, in the hopes that Christ would return soon and establish His Kingdom, where you wouldn't NEED worldly possessions, because He would literally provide you what you needed to live.
If you pay attention post-Paul's conversion, you'll see him asking his converts to pass around the collection plate (so to speak) to support the Jews who, by that point in his ministry, were living in poverty. Yes, POVERTY! Why? Because Christ hasn't returned yet, which was the entire reason for them to give up their earthly possessions.
If Christ returned, they would not have continued in "communism."
thus it'd be a theocracy at such a point.
Democracy would work very well under His guidance as well.
"Who gave you permission to vote on My laws?"
Is what I imagine Christ will say to those (especially the Southern Baptists) who advocate voting over laws.
God gave His laws, which are just. He gave us a good model to use for governments, and from one perspective, the Bible is the ultimate criminal justice textbook! There's no need to try to think up new moral laws (not including laws concerning things that have no moral value, such as how far apart studs need to be in walls or how wide the roads need to be, etc), because HE is the standard for morality, and there's nothing new under that Son....
I'm sorry, I had to, haha.
But in all seriousness, God gave us a perfect law for a moral and just society. There's no need to change or "improve" any of them, because to do so is sinning!
Again, I point to Korah's rebellion in Numbers 16 as evidence that God doesn't like "rule by the people," even acknowledging, even making it my point, that Moses and Aaron were the designated leaders of Israel, and God had already planned to give Israel a king (and eventually, a King), by including laws concerning kings when He gave Moses the laws for Israel, and that such was a rebellion against them (Moses and Aaron), and that while it was within the context of Israel's laws, Jesus Himself made the point that democracy is a bad idea because, in His words:
“Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. - Matthew 7:13

I'd literally bow to any form of government (will bow) He wanted to rule by and be happy.
Jesus tells us how He will rule during the Millennial Kingdom. With an iron rod, sitting upon His throne.
Aka, a King with His sceptre.
Aka, a monarchy.
I find politics have little to do with theology
One's theology affects his politics a great deal!
If he believes in God, and believes that His word is true and accurate, he will promote Biblical ideas, such as do not murder, commit adultery, steal, etc.
If he rejects God's existence, then he will promote leftist ideas, such as homosexuality, socialism, legalization of drugs, etc.
as much as they have to do with power and governance (remembering God sets up kings and rulers of course).
Which simply means that He set up those roles. (Not that He gave the individual kings their power and chose which people would run the governments.)
It means that He established a proper flow of authority on which the above chart is based on.
Authority flows downhill, from God, to governments, to man, to his wife, to her children, and as Bob says, "Even the kid can kick the cat off the couch." anything that goes against that natural flow is, by definition, unnatural, and is unjust, because it goes against the God of justice.
Democracy does that, because its authority flow is circular, as Bob says (or something along these lines...) just like circular reasoning is fallacious, so too an authority flow that's circular doesn't work. You can't have the government ruling over the people ruling over the government ruling over the people ruling over...
It doesn't work simply because there's no actual "final" authority.
That's why it's doesn't work, and why it shouldn't be used, and why Christ won't use it.
