The channel looks like AI muck. They publish every two days?
In re the vegetables themselves, if you read the comments -- the sensible ones, not the argumentative ones -- they indicate that a number of these things are "an acquired taste," meaning that it's a better use of your limited garden space to grow something nicer to eat.
The use of the word "banned" is simply inflammatory and inaccurate.
Attributing the decline in popularity of these vegetables to modern agriculture -- which is what the video does, over and over -- is a suspect attribution because these plants fell out of favor in the 1600s and 1700s while large combines (e.g.) did not appear until the 1800s (and diesel engines did not exist until 1897).
So, all in all, this is clickbait.
