You need a license to drive a car.

You don't need a license to write a book, publish a newsletter, to form some sort of organization and assemble, etc...

Your license can be revoke if (for example) you get too many DUIs.

Your rights to freedom of the press, expression, assembly, etc, can't be revoked.

I'm lead to understand that in most cities you do need a permit to hold a demonstration.
