You may well prefer Everquest's approach, but it'll never happen in WoW-- and EQ is still available to play, if you're interested, although my guess is it retreated at least somewhat from forced dependency to foster solo play too, just due to reality being that's what players want.
That sort of MMO fell out of favor so long ago that I really question whether many of you guys played it in its prime. It's true that forced dependency combined with small non-phased populations controlled toxicity because your server reputation truly mattered, but the tradeoff was horribly grindy solo gameplay, to such an extent that even modern Asian MMO players wouldn't accept it.
Coming back to reality, it's pretty simple. Lots of people enjoy playing MMOs solo, like single-player games with other people running around in the background. That doesn't mean they never participate in group or raid content, they do when they feel like it, but solo stuff is relaxing, less stressful, and they enjoy that. It's a popular playstyle so games will support it, simple as that.
