If your idea is so easy to execute that the only reason other people haven’t done it before you is because they haven’t thought of it, it’s not a great business plan.

Also vibe coding can, almost by definition, only produce code that is similar to code Microsoft already owns, plus given the copyright rules and obvious philosophical questions surrounding generative AI, it could easily be argued that stealing your idea and building it better than you could is what Microsoft has done when you type your idea into Copilot and it builds an app for you.
