In theory, sure. In practice, it's only true when there is broad based respect for the law as a whole. I'm really not seeing evidence of that from this administration or its supporters. To put it very mildly.
For example, according to the highest law in the land, the Constitution, he can't be elected again. Do you really believe that's going to prevent him from running, much less remaining in office should he win, having previously tried to overturn a legitimate election?
The real question is, when he ignores the courts, what then? Normally that would be when Congress steps in. But even if Republicans didn't have a majority, impeachment would still require support from a decent number of them. Based on their behavior to date, how likely is that?
Strict partisanship appears to be a serious failure mode for this particular form of government. As Congress has become more partisan, they've gotten less and less done, both legislatively and in terms of serving as a check on the executive branch.
I like how you focused on "200 years" and not the fact I said "irrelevant". Being old and irrelevant doesn't suddenly make it relevant, no matter how many people like to pretend it is to support their weekly stock pump and dump tariffs on/tariffs off schemes.
And the court here is ruling that the tariffs weren't made in a way that follows the law/Constitution, so your anger is misdirected.
