<So far, you're the only legal person I've read in support of (or at least attempting to defend) the indictment.>

Which is precisely what happens when you choose to spend your entire life in a right-wing echo chamber. (Why would anyone want to live that way?)
Even the NYT article you referenced is just a right-wing opinion piece. Did you read the rest of the paper or just that opinion piece? (I know the answer.)

Here's one "legal person" (of many) supporting the indictment...

"We Finally Know the Case Against Trump, and It Is Strong"
"Mr. Trump, is the 30th defendant to be indicted on false records charges by Mr. Bragg since he took office just over a year ago,
with the D.A. bringing 151 counts under the statute so far. Indeed, the Trump Organizations conviction plea last year also included business falsification felonies."
"Mr. Trump cannot persuasively argue he is being singled out for some unprecedented theory of prosecution. He is being treated as any other New Yorker would be with similar evidence against him."
