You're free to do it without Medium anytime! But if you want to use this platform, there's a cost.

I don't know how you got to be so lucky as to be able to live without making any money for your work, but more power to you. I have to earn money to live, and writing is the profession I'm best at. Please do let me know your secret for not needing to be paid for your work. I, too, wish to spend my days not worrying about the cost of my basic needs.
