I've seen several channels, the one pushing it the most that I've seen is Grounded Life Finances/Travel. Their schtick is "retire now and travel full time". They even basically tell people how to invest money.
Naturally they have a course at around $200 or so. Also, their "retirement" is running 6 YT channels and supposedly they have some sort of modeling business. I questioned them once about if they're running 6 YT channels, that's not really being retired. I was told "We consider retirement being able to do what you want". Last I checked, retirement meant you weren't working anymore.
Everything they own is in a suitcase and backpack each. They went through a whole thing about selling everything, but the guy still carries an Xbox with him around the world.

And they also talk about different jobs you can do if you're "retired" and travel full time. Of course, they say teach English. Most of these folks don't have enough of a grasp of English to teach it to anyone. The other one was giving tours in one of these countries they go to. As they told it, the gist seemed to be pay for/go on a tour, take some notes and then start charging people for a similar tour. Sorry, but if I show up for a tour of a cultural/historic site in a foreign country, and some "retired" American expat is giving it, I'm asking for my money back.
Most of these folks act like it's their greatness that makes the money, no it's the ad rates on YT and the garbage you sell to people as well as freebies you seek from companies. These idiots hawking something instantly makes me not want it.
