Technically, SCOTUS, as the highest court, isn't beholden to anyone's precedent. This year's SCOTUS is just as legitimate as last year's, so they always have the power to overturn past decisions. Lower courts have to follow what higher courts decide, but SCOTUS has no higher authority. And sometimes, like in Brown vs. Board of Ed (which ended legal segregation), it's a very good thing for the Court to overturn its past decisions.

But in practice, to non-lunatics, stare decisis (the legal principle that says not to overturn, or even consider, topics that have already been decided in the past without an extremely good reason) is an incredibly important prior to bring into any discussion. If the court actually uses its power to completely rewrite the rules of how government works on a whim - and let's be clear, that's what this decision does - then there's no way for anyone to ever make a plan. Nothing is stable.

Unfortunately, at least 5/9 of the current Supreme Court are either lunatics or blatantly corrupt. Chevron was decided unanimously for a reason. There is no way to administer a modern state without that concept - which is why right-wing extremists are so happy to see it gone, because they don't want the state administered.
