You’re very condescending
The difference between your land and stocks is that selling a square meter of that land had no impact on the value of the remaining square meters.
Sure it’s possible for someone to buy all musks shares at once, just like its possible for someone to offer 10 trillion dollars for it.
A good example, though not entirely equivalent, is bitcoin. If theres a million bitcoin in the world, and bitcoin is valued at 80.000 per bitcoin, it does not mean there’s 80.000.000.000 of wealth in bitcoin, because only the first few bitcoins trade at that price if everyone sold off.
Of course that wealth can be leveraged (which is done mostly for tax purposes), but it does represent a risk to the lender. If you have 100 bitcoins representing 800.000.000 they’ll allow you to leverage like 100.000.000 in loans against a small interest. What they definitely will not due is get anywhere near the 800.000.000 estimation, because there would be significant risk the real value does not match its on paper estimate.
We WILL see something go terribly wrong with overleveraged billionairs. It’s part of Murphy’s law.
None of this pertains to the post I was replying to though.
