I think Names can only take so much Space in Youtube. And Aragorn didn´t completely abandon his old Name, Ellesar was just another Name he took onto himself, so I guess both can be counted right. And if he had chosen Ellesar, nearly nobody would have recognized him:D

He took it on as his royal name, just like any other royal taking a throne, that is how you would address them. But, you are right, if it weren't for the picture no one would know it was him

I´m pretty sure, at least Frodo would still address him as Aragorn or Streicher.D
But yeah, sadly so...People should learn this Stuff in school, but instead we have to read classics that aren´t 0,1% as good, asTolkiens Works. At least in Germany.

amerifag here, we read the hobbit in school but that was in like 6th grade so that doesnt even really count
