That “theoretical value” is used as collateral to borrow money for billionaires expenses.
And unless the loan is defaulted on, it never stops being theoretical.
Why is it theoretical only for taxes purpose, but very real when you talk to a bank?.
Loaded question, it's not any less theoretical in the latter case.
Also, it's entirely possible for some scandal to plummet the value of a stock overnight, such that the value that was used as collateral is now not worth nearly that much. But it is the lender's prerogative to decide to take that risk, it's no one's business other than the lender and the borrower, both private entities.
Is that your opinion on properties taxes?
Yes, property taxes should not be a thing.
Hypocrisy detection failed, lol.
And at this scale, it’s not “stuff you own”. You may have an issue assessing what a billion is. Do you know the difference between a million and a billion? It’s roughly a billion…
You may have an issue understanding the simple phrase "stuff you own", since you're here apparently arguing that beyond a certain valuation, assets are no longer assets.
