There are plenty of people who understand the change that just don't want it. Saying it's "only going to have a positive effect," is an opinion, not a fact.
The more I read this thread the more I shake my head, the constant "people don't understand," "people are afraid of change," constant awful sarcasm, etc etc is incredibly patronizing. This isn't hard to understand, at all. Just because in your mind, there is no reason to disagree with you, and that your argument is infallible, doesn't mean that it is. Your inability to understand why people disagree with you does not mean that they are simply finding it hard to understand or are "afraid of change." Stop projecting.
