Your argument is called Pascal’s wager. My main objection is there’s a lot of superstitions to try. If you want maximize the benefit of a strategy like you’re describing, you have to worship every god of every religion, obey every limitation on what you can do in every religion, superstition or conspiracy, take every supposedly magical medicine, ect. They all seem equally unlikely, but they are all believed by someone and if true would have huge benefits, so by your logic I should follow all of them completely. Except by doing that I am sacrificing most of my life for the tiny possibility of a benefit, rather than making the most of the life I know I have.
