Exactly. Many times I'll ask people from another domain, "Why can't you just...", so that they can explain why that seemingly simple idea won't work. And I know full well that it won't, I'm just not sure why. But another problem with the idea of banning speech is that "just" recognizes that there are levels of complexity, effort, and risk. No, there is never a solution so simple that it is zero effort and risk. But there are certainly some solutions that have more or less effort and risk than others. And if you're asking if you could just do something else, you're implying that the something else is less effort or risk - not zero effort or risk. I have worked with people that have a similar approach as never say "just" in that they insist that every problem is hard and should never be trivialized. That's a reasonably wise stance to take as a default in software development, but kills the recognition that some approaches are, in fact, easier than others.
