A point.
People are posting about whether they "need" any strings other than EADG on their bass. To me that could have one of two meanings:
1. It's a cover band and none of the original material has notes lower than E, so why bother with an extended range bass? Valid; I bought a P-bass for the first time since the mid 80s a few years ago for that reason. The P-bass is simple, looks the part, and lacks nothing for the party rock band I play in. Well, there is the low D in Uptown Funk, but still.
2. It's an original band or a jazz group. Conceivably there the player could use a low B or high C if they chose to, but they'd rather not. That to me bridges the concept of need with "prefer". We live in a world where those two concepts are always conflated.
By the way, I'm crummy with chords and don't play many on my 6 string. I also think a bass player risks clashing with the notes the guitarist is playing when they play a lot of chords in a group setting - it's one thing for the guitarist to play a 9th two octaves above his root, another if the bass player plays a 9th that ends up being a single whole step away from the guitarist's root. The latter will result in dissonant mud - we need to be aware of that as group players.
I use my high strings for soloing in a jazz or arty context, because I think the high strings enable the bass to be heard differently as a soloist instrument than it is heard as a foundational one. A 6 helps me serve both roles as I get to.
