Well, the good part about these metaverses is that they can actually create an income for people who own this virtual land/resources. I personally know people who earn a substantial income from owning land in games like MegaCryptopolis.
I understand the skepticism, but to me, it seems like a better model than you paying a video game developer for virtual resources and getting nothing in return. With these metaverses, you at least get to own the resource and perhaps even make money off of it.
