Perhaps because they have domain expertise not generally available outside their field. Do you also argue developers have no reason to think they should be given special consideration in W3C's and IETF's standards processes?
I disagree, I think they have selection bias. I also think that they are more like a CPU than they are like a developer. The legislator is the developer. The constitution (of whichever country you are in) is the standards body. It is their job to execute the law, not to make it.
