Very true. Seems like a scam to me, but you are right of course.
I do wonder whether his income can be protected in the same way. He may have layers of protection, but income is income, and the IRS is the IRS. He has to pay taxes on deposits that end up funding his personal lifestyle. If, for example, a court orders that his residuals from Boss Baby go instead to any plaintiffs who succeed against him in court, then Warner Bros or whoever it is will surely fork the money over to the court-ordered account rather than just pass it on to Baldwin. If Baldwin is smart, he'll get some kind of structured agreement, but his cashflow may be at issue. With the budget for his household alone, he is in need of spendable cash. Real estate taxes paid by him out of, say, an LLC, would still be recorded as personal income to the owner of the LLC. You can't simply buy and sell through an LLC and never pay tax on it.
Similarly, a court could attach part of the funds dispensed from any entity in which Baldwin had ownership, IMO. Personally, I don't think he has a lot of cash. Just a feeling from listening to him and Howard Stern talk about it. At least not compared to Howard (and both men do pay taxes on personal income).
Baldwin should probably put what cash he has into the hands of, say, a family trust if he hasn't already, but as far as I know, a person can't have hundreds of thousands of dollars flowing into a bank account, from which they personally use funds to pay for nannies, trips, jewelry for their wife, wife's procedures, own cosmetic procedures, even own health insurance. Those have to be treated as a form of earnings or salary - whichever works out better taxwise.
He's going to take a huge hit from this and, IMO, was already cash poor. Which is why he was scrambling to do various projects (and is still renaming, rebranding his projects that are barely keeping themselves afloat - his podcast doesn't produce itself).
