... Individuals don't fit well into boxes. ...

Well, duh... isn't that a definition of "individual?"

There are a few sub-meanings of the word "individual," and your summary of the cited video seems to want to conflate the various meanings.

...
individual

1a of, relating to, or distinctively associated with an individual
an individual effort

1b intended for one person, an individual serving

1c being an individual or existing as an indivisible whole

2 having marked individuality, an individual style

3 existing as a distinct entity : separate
...

It looks like definition #3 is intentionally mixed with definitions #1 and #2.

That's a shame, because the video cited seems to be about something quite different.
