I explained this to you in a post back in late March.
The best way to manage a company is to line up future income with future expenses and not keep too much cash on hand. The better this can be done, the less cash needed to be kept on hand. Given the genius level IQ of President Trump (and the brilliant people he surrounds himself with) the in and out cash flows were probably very well aligned.
If President Trump had all the future assets and liabilities lined up and then was forced to sell a huge piece of real estate (really fast and at a huge loss) he’d lose out on the future income to pay the future liabilities.
If the AG and judge weren’t so blatantly biased against him they may have just allowed him to post the title to one of his buildings (worth considerably more than the bond) but they were trying to do irreversible damage to him and his company and insisted on cash.
