The laws underpinning and protecting their ownership, as well as the institutions enforcing them, are historical holdovers and were never truly legitimised. They also largely go against justice, freedom and the pursuit of happines, which they largely champion as their goals.
At least you could think about it that way.
I’m not seeing how that makes any of it illegitimate. If you make something you own it, right? Why should a business be any different?
At the end of the day because the assumption that it shouldn’t be any different for a business is flawed. And specifically because we live in a reality where this assumption is largely taken as truth and as a result laws get written by Musk Bezos Koch Gates … and / or the companies they use to do their bidding. Which often enough have very bad outcomes, and are obviously bad laws, not only in hindsight.
While they are supposed to be written by the people for the people. Democratically. The Private company in this way wields authoritative Power over it’s employees and with this power it often enough opposes or distorts the will of the people because the few owners get outsized control over the actions of many workers customers and so on. As such if there isn’t a limit to private ownership of Capital/The means of production/Business there can never be anything more than a hollow democracy, a democracy where the word is used to describe itself but the spirit of the word can never be reached.
We are on lefty Memes here so a bunch of people likely want a less hollow and more true democracy in this sense. Which is why it should be different for a business or at large scale.
So basically what you are saying is the more successful a business is, the more of it we should steal away from the rightful owners?
