Argument from authority is a pernicious fallacy, and typically effective too. You were right to call it out. I must admit I overlooked the sarcasm, however.

> I must admit I overlooked the sarcasm, however.

Don't feel too bad; until I read the next response I was in two minds about whether sarcasm was intended or not.

It's bloody hard to tell, sometimes :-/

it can be for some

If people say "believe me" at the end of every second sentence you should doubt them. Not thinking of anyone in particular.

Oh, I was bamboozled.

Human beings can't evaulate the truth of things based only on the argument. Persuasive liars, cons, and incompetents are a very known phenomenon. Most of human history we misunderstood nature and many other things because we relied on 'good arguments'. Not that we need it, but research shows that human intuition about the truth of something isn't good without expertise.

When I need medical advice, I get it from someone who has convinced me that they have expertise; I don't look for 'good arguments' that persuade me, because I don't know what I'm talking about.

I have expertise in other things. In those fields, I could easily persuade people without it of just about anything. (I don't; I'm not a sociopath.) I imagine anyone with professional expertise who reads this can do the same.
