Monetize Player Created Worlds?

Curious if there was any thought for allowing people to monetize their game worlds down the line? Maybe not until the product is further along, but as I’m creating my own world I find myself thinking I would like to spend a lot of time really brining it to life, but that I just don’t have the time to dedicate to without a potential payoff. If you could post worlds, or content packs for sale it might really expand the amount of user generated content being created.
