What about the products of my labor that I create from scratch? Can I decide what laws govern that too? You know, like taxes?

That idea went out the window a long time ago. Now we are all beholden to each-other and society on some level, so best we deal with it and solve these anti-competative issues and predatory platforms, otherwise let's agree that it's completely immoral and stop cherry-picking "moral rules" based on what we find useful at the time.
