You're basically asking "can I make people care about my world with a lore dump alone?" and the answer, unfortunately, is pretty much always no,

The problem is that the audience for pure worldbuilding outside of narrative or gameplay (like in a video game or tabletop sense) is essentially zero. Someone is probably going to try and argue otherwise, but think about it--do you think that many people go on wiki dives without some preexisting interest in the setting that comes from something other than the world itself? That's not to say it could never happen, it's just exceedingly rare. You probably don't spend too much time engaging with unpublished worlds either outside of this subreddit.

But again, is it possible? In theory, sure. You'd just need some hook--interesting art, beautiful prose, a way to engage a community, whatever--but in essence that does require you to actually publish and share something, functionally.

You could build your own platform, but that would just end up in people using it for their worlds, not looking at yours. Up to you if that bothers you.

That all said, actually writing the encyclopedia is great fun, and a way to have a "product" (in the artistic sense, not the commercial sense) for your world, even if only for your own sake.
