Will SCOTUS continue to act as trump's rubber stamp, regardless of the clarity of the law surrounding IEEPA?  That would definitely be the easy way out, as well as pleasing their lord and master, trump.
IF they follow the rule of law, tho, unwinding all this tariff money is going to be a total clusterf*ck.  As well as tearing down the one policy trump constantly brags about, even as everyone else is beginning to wake up to what it means to the pocketbooks.  And one thing I've not heard anyone mention a word about, is what about replacing the tariff money if his actions are deemed to be as illegal as the law has already stated they are?  He's killed about every other policy that could fund the government with tax dollars... including the IRS.  And we know his mobster friends aren't going to chip in THAT much money just to have him save face!
I don't know what it would do the U.S.... and I suspect it'll be horrible no matter which way they rule.  But I REALLY hope this law is as transparent to everyone to such a degree SCOTUS can't cover trump's backside on this one.  Add to that, the tariffs are really dragging down the economy, and hurting his billionaire friends' bottom lines.  So even THEY may not have his back with SCOTUS on this one.  There is only one thing I know for sure... ETTD.  And it's looking more and more like that includes our Country.
Frankly, should SCOTUS rule WITH the law (as they should, and in accordance with the way the lower courts have all ruled), I think we should claw back all that money from Trump, himself.  After all, he's done nothing but steal OUR money since he walked into the office.  And all these shenanigans with the crypto and meme coins, etc., should cover a bunch of the deficit he'll have caused by giving the lower courts the raspberry and blowing off the Rule of Law, IMO.
