I agree that there is a lot of inevitability in this result. This is often a debate in the implicit context of "we should make the government even stronger, probably socialism or communism", but in those cases instead of two entities who at least
sometimes struggle for power, we're just giving up and giving all the power to one entity.
So, if the problem is that corporations and governments tend to get too close to each other, what exactly is the nominally-better solution that we're supposed to be comparing against?
What if this is already just about the best we could hope for? It does sometimes seem to me that people have this implicit idea of a world in which, basically, nobody has any power, or everybody has the exact same amount to an arbitrary number of decimal places, but even by the standards of Utopianism, that's Utopian. What, exactly, is the goal of this conversation?
It'll differ for different people, of course, but it's still a valid exercise. There is a lot of "1. Identify problem. 2. Propose solution. 3. Fail to observe that proposed solution couldn't possibly have solved original problem, even if it worked as designed."
(For another example, see the last few mass shootings, and the subsequent proposed "solutions"; without reference to whether or not they would be good idea and whether or not more gun control is good or bad, it was frequently the case that even if the proposed solutions were in place and perfectly, unrealistically functional prior to the incident that the solution still wouldn't have prevented the event, e.g., "more background checks" that the shooter still would have passed, etc.)
