Roblox works like this, and it allows for studios of multiple people to work on content easier. If you make the money easier to distribute to collaborators, more people want to make bigger and cooler content for the platform.

Group payouts can be restricted to only creators who already have economy access so it's not a way to turn credits into money for non-creators.

In addition to having 1 time payouts, being able to set certain members to have revenue share of the group/"studio"'s projects (again, like how Roblox does it) would make large collaborative projects SIGNIFICANTLY more viable. The tax hassle around paying contractors regularly is a major disincentive.

This could be very beneficial for both avatar and world creators! Responsibility of the uploaded content making money would ultimately be under the owner of the group, content could still be uploaded under their own account. But funds for specific things could be directed to the group instead.
