Is your feature request related to a problem? Please describe.
An user can create a dataset, as long as they are the owner of that dataset.
Higher tier user’s can create datasets for other people.

Describe the solution you'd like
Modify base user account permissions and merge them with "data owner" role.
This makes the platform a more traditional content creation and sharing platform.

All users are potential data owners, and can create datasets.
Once they have created a dataset, then control access to it.

Probably just make a new Dataset creation form, that has the owner, and user group information as read-only, for low tier users. This will also simplify dataset creation process for new users, which reduces the barrier to entry. Probably the support user should be auto-filled as the current user as well.

Additional context
Lots of policy tweaks on this one.
I'll have to decide whether the data owner role is still relevant, or should just be merged with "user".
Alternatively, I could give the "data owner" role to users once they create a dataset.
