Yes. The public can choose to create a legal structure that does not let private entities grow so large, but we have not chosen to do so, and that choice does not mean that private entities are de facto public.
Those structures already exist. They are typically categorized under anti-trust category. The issue is that between regulatory capture, revolving door, dual party system and average voter distracted by carefully selected social issues, the choice is theoretical. I am not automatically arguing they should be public. I am saying they should be cut down to size.
I've heard that a countless number of times and yet nobody has been able to come up with a good way to do that or even demonstrate that it needs to be done, or demonstrate what it would accomplish, or demonstrate that it would not make the problem worse. Every congressional hearing I've seen has ended with a failure to even explain the basic reasons why it's being done. It all seems to eventually revert back on a list of personal grievances that some individual or group might have with the company, which do not require antitrust action to correct, and the judges notice this and throw the case out.
I would be much more in favor of something like GDPR, but the US has no political will to enact something like that, it's all personal grievances all the way down, on both sides of the aisle.
