If someone is making that claim surely they can clarify exactly what too much is and why.
How do you expect anyone to take this suggestion seriously? How do you expect actual policy to be set without clearly defined boundaries of acceptable behaviour?
But hey, you seem very sure of yourself. Do you think there is any amount you consider too much?
Will every single private transaction be subject to scrutiny by some sort of administrative panel that takes into account the current holdings of the prospective buyer?
It's curious to me that there is such a visceral opposition to Bill Gates owning some farm land in a place neither of us have ever heard of when he has so much more direct power over all of us through Microsoft.
I don't think that there is a specific quantity of stuff that is too much stuff for one person to own. I think that there are issues with wealth concentration but I don't think it's absolute.
The issue isn't that one person owns a lot of stuff the issue is that one person owns a lot of stuff while most other people own nearly nothing or are in debt.
There are alternatives to every Microsoft product. Comparing vital resources like food/water supply etc with a computer operating system makes no sense.
I don't think anyone is proposing any laws here, at least not yet. Simply pointing out the fact that one individual is in the process of amassing insane amounts of a vital resource which will result in him having insane influence on something as basic as food. You seem to be more concerned about causing a minor inconvenience to someone with crap ton of money (if and when some laws are enacted) than the risk of one individual having power over vital resources. Already some 80% of meat in US is controlled by 3 companies, 50% of seeds are controlled by one company and so on. The situation is only getting worse.
I am going to stop arguing. By all means, please support billionaires with hideous monopolistic past/insane amounts of money and let private, unelected individuals influence policies etc if that is what you believe in.
For example, Larry Ellison's island in Hawaii, vs rural undeveloped landlocked farmland.
