As much as I agree with your point -- and I bet it gives people pause when you deliver it! -- I think that the reason they're giving is somewhat valid, but just worded very poorly. AIUI, what they actually mean is the social interaction aspect of things... which, coming back to your point, is still pretty twisted.
However, things like forming friendships and relationships and dealing with social adversaries, while bastardized, is still real. Of course it's not like these things can't be done outside of a school setting -- it's just the most likely place for a child with little or no options for significant physical mobility.
