Interesting... this has been something I've postulated for several years now. My reasoning had most to do with our vision system. As we perceive distances, the distance between something 10 feet, 100 feet, 1000 feet away, etc, becomes less about knowing the absolute difference and more about relative distances; someone is more likely to determine that something is 110 feet away than they are to realize something is 1010... but realizing something is 1100 rather than 1000 feet away will feel about as off as suggesting something 110 feet away is really 100. Our vision measurements are further reinforced as we observe parallax scrolling as we are driven around the country in our youth. I've also felt that teaching a number system that is linear means that it is harder to understand the difference between 100 and 1000000000. Even many adults find it difficult to understand the magnitude of numbers when you approach a billion or a trillion. I think this is largely because we are taught to think in a relatively small range of the number line and perceiving numbers outside that range, we try to relate it back to what we were taught in schools. I'd love to see schools teach a logarithmical number line instead of the linear system kids are taught today.
