So a bit about me, I'm a very practical-oriented, some might say cheap person. I look at excessive luxury as a moral failing at any wealth level, either because you should be giving that money to charity, or because you should be saving it so you don't end up needing charity yourself someday.
However, finding a woman with a compatible mindset has always been a challenge, and it seems to be getting harder every year. I've been dating mostly online for a good while, and prior to the pandemic I pretty much never ran into a woman with a lot of luxuries in her life. Now it seems like almost every profile features a woman showing off a LV/YSL/Gucci purse that cost 4 figures or more. These luxury brand purchases are the hardest thing for me to relate to, because it's just the brand - it's purely to signal that you could afford to send some corporation your hard-earned money for virtually no reason. And you don't have to take my word for it, luxury goods are booming, especially among gen Y and Z.
Problem is, I'm finding it harder and harder to cut this massive chunk of the population out of my dating pool. I'm also attracted to the look of feminine accessories like jewelry and heels (isn't everyone?). And while I don't care if it's cheap accessories, there seems to be basically a 100% overlap between women who wear feminine accessories and those who like spending lots of money on brand names. I kinda hit rock bottom recently when I went on a date with a low-wage worker which made me excited that maybe I finally found someone down to earth enough, and then even she showed up with a $1200 purse (yes I looked it up).
So it's time to pause and seek alternative perspectives. I want to keep looking for the cheap-yet-feminine woman. But at the same time, I feel increasingly like I'm being an extremist. Is there some way I can understand the need for luxury brand purchases differently so I can find it more acceptable in a long term partner?
To give a serious answer: The short answer is probably, the long answer is no.
The opinion was deliberately vague on that issue. A dissent said they could under Roberts' opinion, but Roberts calls that "fear mongering" without elaborating whether that's true or not.
It's also a pretty complicated opinion so bear with me. The whole thing comes down to this vague idea of official vs. unofficial acts which are supposed to be immune according to the court. Really, there's multiple factual allegations and the court said each one has some level of immunity (and if you think these are full of contradictions, I know):
Conclusion: Ordering an assassination of a rival certainly sounds most like the first - the president has several official duties relating to giving military orders, and the military is part of the executive branch. The FBI is also part of the DOJ, so if Trump can order the DOJ to do something criminal, that itself could be an assassination. But as described in the article below, one could make an argument that no, the opinion doesn't actually say he do that with the military specifically, because congress has some powers relating to war (not convincing). However, to be fair to that opinion, this immunity ruling is such a stinker that lower and future courts will limit its holding as much as humanly possible. Plus seemingly contradictory aspects to it (Trump can order the DOJ to do things he can't do himself?) could be used to argue for exceptions to the overall immunity. But reading the opinion at face value, yes the president could order an assassination, and even fire generals who refuse to pass along those orders.
Longer answer though: This is the real world. If Biden gave such an order, it would likely result in a coup and an overthowing of the Constitutional order as a whole. And if order were somehow restored and Biden brought up on criminal charges, you could be your life that the 6-3 Republican majority on the court would find a way to either limit or perhaps overturn their prior ruling as it pertains to Biden.
For an alternative perspective on the same topic, here's a center-to-slightly-right-leaning law professor's take on this which does a pretty plausible job sane-washing the opinion.
