Unfortunately, I can't really watch a few hours of movie like that and if the movie makes solid points, I'm sure they could be summarized into a paragraph or a few. I suspect that the fallacy I'll see in it, is claiming that something that could work on micro scale with 100% willing participants that agree with it and don't want to abuse it would work on the macro scale. You realize there are also tons of working communes out there than can be presented as evidence that communism works, right?

If I trade my labor for it then it is mine, not theirs. My labor is certainly not someone elses property unless you argue that all people are slaves of that which some people created... governments.

I argue that while laboring, people take advantage of the economy of the country they live in and it it's not immoral for them to be taxed to sustain it. Economies benefit greatly from infrastructure, contract enforceability, a reliable court systems, a reliable banking systems and so on. Whatever you do, you are getting all those benefits and you are taking advantage of them. You get benefits, you also get burdens. That's how society works and if you want to live among people, that's always going to be the case. There is no real alternative. Thinking there is an alternative is utopian.

My claim is that modern people are more imprisoned, not more oppressed.

I wonder what data you have to support that wild claim... My guess would be none. I mean no offence, but comparing the way we currently live, the freedom we currently have to feudal peasants and coming up on the side of the peasants is ridiculous and delusional. Let's stop with the big words and platitutes and look at it practically and see what we can do now and what they could do back then.

We have more choice in employment. We have more choice on where to live in the country we are citizens of. We can vote for our governments. We can choose to move to a different country. We have access to the internet. We have freedom of speech. We can say no to a noble that says then have the right to sleep with a bride on her wedding night. We can be thrown in a cell only after a trial by laws that are publicly known and passed by the governments we elect. We can trade stocks. We can start a business. We can can trade cryptocurrency. I can probably go on and on and on. What freedom to peasants had that we don't besides knowing their enemies (which is not a freedom)? Please be specific.

Slaves none the less.

Slaves by what definition?! If you are looking for absolute freedom, you are never going to get it as you will always have other people around you whose rights and well-being will always put limits on your freedom (as yours will put on theirs). Thinking there is a perfect solution to change that is what I call an utopia.
