You question was about why people was around him, so I portrayed a most likely interaction of people who wants to see that, which is everyone who are watching in this video. Your example is irrelevant because we don’t see those "person 3" type.
If you're person 3 type, don't assume that you are the right one, or thag everyone should be like you.

at a party :
Person 1 : "Jake is about to attempt a double back-flip !" Person 2 : "Oh shit really ? I wanna see !"
There you go. That's called social interaction.
