One of the issues that is being cleared up in the three emoluments lawsuits is the definition or application of the word "emolument." Does it mean profit only or did the Founders intend the word to be used in a broader sense?
The Founding Fathers wrote fairly extensively on it. The primary goal was to prevent the President from being influenced by bribery, gifts, profits, and other schmoozing, both tangible and intangible.
You're not a constitutional expert and neither am I, so I'm not going to get into an interpretation argument here. My point is simply the issue is unsettled.
I've never even tried to engage in an interpretational argument here, because, as I have stated numerous times, the Emoluments clause has never been adjudicated. (and I've used that very word nearly, if not every time I've discussed it). And since it's never been adjudicated, and I have no clue as to how the High Court might rule, it's impossible to make an argument on interpretation.
My personal opinion is to use common sense. Profits from existing businesses, during the course of normal business, unless they are suddenly wildly out of whack since the election, shouldn't be considered an emolument, since they aren't totable enough to be noticed. Plus, in Trump's case, the Trump Organization ceased doing any and all new international business since the election, and neither the organization or Trump has made any overtly obvious attempts to solicit influence, foreign or domestic.
Congress is constitutionally enumerated as the sole arbiter of what is and is not acceptable under the Title of Nobility Clause. Congress can consent to something, either by formal vote or by tacit silent consent (and they have in the past done both, and appears they are doing the latter currently) or they can refuse consent outright (as they have also done in the past). All I know for sure is, the people who elected Trump knew full well about his businesses, and they elected him anyway. There's no getting around that. And unless he abuses the privilege, they're OK with it.
Believing it wrong for Trump to maintain business interests while he is president that conflict or potentially conflict with the national interest, I'm watching these cases with great interest. I am hopeful that the courts will also see this as wrong and so rule.
So far, there is no evidence that Trump has acted in favor of his business interests to the detriment or in conflict with the interests of the nation. In fact, there are many examples of Trump putting the nation's interest above his own. There are, as you note, plenty of "potential" conflicts. The potentials, the what-ifs, the might dos, those are the bread and butter of the evidentiary catalog of the anti-Trumper looking to bring him down. Whether it's the possibility of Trump having his finger on the button and killing us all, to him getting us into endless wars, to him crashing the stock market, to him using his position to enrich himself, they all fall apart as nothing more than what people are afraid he might do, and never rises to the level what what he actually did do. They want to take a "might could" and turn it into a crime worthy of impeachment. It's breathtakingly infantile.
