You can't just get rid of 100% of bad things about regulation and keep 100% of the good things about regulations. It reminds me of people who start open relationships. The upside sounds great, but there is a huge potential for downside and you may not fully appreciate that until it happens.
Other analogy that may be relevant are cases where casinos had slot machines with bugs awarding more prizes than the casino intended. In some cases/jurisdictions the courts ruled in favor of casinos, that the money was awarded incorrectly and should be returned; but in other cases/jurisdictions favored the winner, saying that the winner did everything right according to the rules of the game and should keep the winnings.
Also the Pepsi 349 Scandal in the Philippines in 1992 comes to mind [1]. In that case courts side with Pepsi, but I suspect that money has some inertia in Judges minds, so it was easy to side with Pepsi when it haven't paid yet. I suspect that if all that money had actually been automatically transfered to the many winners, then Pepsi would have a much harder task to convince the judges to make everyone transfer the money back.
Right?
If people signed a paper contract and a software system was designed to implement the contract, but the software system erroneously (through a bug) did something that went against the contract, that would be an erroneous payment. But if the code is the contract in a smart contract, bugs aren't contract errors.
The thing about crypto and ownership is that the blockchain is not the final arbiter of legal ownership, and that qualifier matters in a lot of cases.

if you think about money as a commodity, to be consumed, transformed, redeployed, similar to let's say... corn. what would you do, as a grain processor, if your supplier decided to show up with 500k bushels six months too early?
Your example mainly deals with futures (a type of financial instrument), mainly because you have agreed to pay within a tight schedule, which does not allow you to service them too early nor too late. Also, you forgot that money was invented to be widely fungible (okay, you can argue if this is true in this age but I argue it's still largely is) meaning that it can be (relatively speaking) easier to convert to corn, stocks, or generators (for example), which is different from corn which is only usable to a subset of people, meaning that you can only deal with those people which needs or wants corn (for example, you cannot easily get generators with corn).
additionally, the lenders to revlon took on both an expectation on money in the future and a non-zero default probability. maybe you can say it is fine for money in the future to be money in the present, making the layman assumption that the carry mechanism exists every single day from the date of accidental payment to the date of actual payment, but the lenders cannot also give up the non-zero default probability. that's their obligation in return for full future payment. but since payment and the obligation are inseparable, i personally see no difference between early payment with no obligation and shylock's taking of a pound of flesh and all the blood along with it.
Money is not a commodity; it's a quantity of fungible tokens (plus the other stuff that makes it money). Money doesn't expire; the closest thing is tax. Yes, it's worth a different amount as time goes on, but debts are generally money debts rather than value debts.
