I know in context you don't intend that but just a pejorative based around the fact corporations are a legal structure. Although I'm always puzzled by what the actual problem with this is. And I'll go on a tangent from the topic.
The legal system is fictional in basically the same way a corporation is. So is all other aspects of a government. Even the legal rights that a real person has are just about as far removed from flesh and blood as the legal entity of a corporation is from the brick and mortar and people that make up a corporation (for those corporations that have such corporeal bodies).
Having almost no appreciation for legal systems or their history, I would also guess that the idea a stroke of the pen suddenly gives birth to corporations which spread their ruin across the earth is backward, or at least much more complicated. Usually it is the legal system catching up with reality, solving problems like regulating existing practice of the time. Laws are shaped by society as much or maybe more than society is is shaped by laws, in my opinion.
I mean, argue specific problems of corporate law, but the general disparagement of "legal make-believe" I don't understand. The entire legal system is built on it, there's a lot of good things that are done with it.
There's no metaphysical Lockean value production going on inside of a corporation. When it produces value, the value it produces is the value that its employees produce. Waxing poetic about the value of corporations is thusly mostly a game of smoke and mirrors that obscures the real source of that value (the humans doing the work), and detracts from the actual advantage that comes from incorporation (i.e., solving the coordination game and thereby extracting more value from workers).
In my experience the value of incorporating has not been to hire people but the legal protections and ability to create certain tax structures for retirement planning that benefit the owners.
> A corporation doesn't require any employees.
In reality some employees are required in order to keep the corporate designation that allows the use of certain retirement plans.
Likewise, unions aren't "politically created structure": they're not created in a top-down manner by the state. They're a form of collective organization and bargaining, the sort that is singularly responsible for the quality of life and workplace protections that we all take for granted.
Then why are you so upset that people don't want to create the "politically created structure" version of unions? Why not just organize as workers and call yourself a union? Can even create a workers party, like they have in basically every other single other developed country, and then that workers party can stand up for your rights. But that workers party isn't a union. Basically every single developed country except USA has labor parties. Democrats aren't a labor party, they are a party of mostly lawyers.
It's fair trade in the beginning because of high risk during the founding of the company but the tradeoff becomes less fair as the risk lowers and the company becomes more mature.
If we were truly looking for more advanced forms of organization beyond the status quo, I would expect that economic imperialism would not exist. Instead, even more aspects of basic society are capitalized and in recent decades also codified using the inflexible mechanisms of computer code. The last remaining hold outs do so at their own expense[3]. So no, I don't think we're exploring the possibility space of superior economic technology, we're stagnating.
