>>109494915The issue of npcs who lack internal dialogue and are distressed by silence is more prevalent than people with inner monologue may realise which likely contributes to why your friends who don't watch vtubers say this. They literally require noise to fill their head because nothing is going on in there.
But really your question is strange because it applies to literally anything, "why listen to music when you could listen to nothing?"
People who watch any kind of streamers usually have a level of parasocial relationship where it feels like you're with company. This predates vtubers. When the Super Best Friends Zaibatsu broke up people said it felt like their parents divorced.
I usually do chores or eat while watching youtube. It's nice to have girls who agree with my political views and I get updated on current events by smuggers.
