The fact that your suggestion requires switching browsers which loses functionality means it's not an option. My statement is accurate. If you simply remove Flash, you can't view some websites, which is not an option. If you switch to Chrome, you're back to using Flash, albeit a browser version, but you lose functionality that existed in Safari.
Again, you can do what you like, but removing Flash or switching to a browser other than Safari is not required to keep Flash under control.
