What an interesting position. So, ultimately, you feel that, if you can't personally shatter the laws of reality and time, then you don't have "agency"? I literally cannot even imagine trying to DM for you. I feel so sorry for your past DMs. The story's either collaborative, or it's not, and it seems you are just completely unwilling to collaborate within the confines of a given world. You don't want to play RPGs, you just want to write fanfiction.
