Your argument applies to everything that requires a mass movement to change. Why do anything about the climate? Why do anything about civil rights? Why do anything about poverty? Why try to make any change? I'm just one person. Anything I could do couldn't possibly have any effect. You know what, since all the powerful interests say it's good, it's a lot easier to jump on the bandwagon and act like it is. All of those people who disagree are just luddites anyways. And the luddites didn't even have a point right? They were just idiots who hates metallic devices for no reason at all.
