I think it's because NAs are far more socially focused; if their close friends aren't playing it, they won't play it. A lot of NAs play gatchashit, MMOs, and similar low effort games where you can get a lot of people together easily and none of them have to do very much. VR games are higher effort than something you can minimise so it's far more difficult to convince multiple people to join in. They generally switch games quickly as well; they'll play when there's updates for a few weeks or a FoTM, but rarely stick with one thing for any longer. VR games are not released often, so even if they do play it, it burns out fast and may be exclusively in lobbies that never even reach the thread.

EU is more of a single group as well, whereas NA is very strongly divided into subgroups, so if an EU can convince the same percentage of people in what they perceive as their group to play something, they'll get a larger lobby than if an NA convinced the same percentage of their smaller sub-group.

I don't think the difference is inherently geographic, as the problem was reversed in 2018 with NA having far more events and lobbies than EU, while EU had problems even forming VRC meetups at times. I guess it really comes down to the handful of people who have most influence over a timezone at any given time.
