Hypothesises on ASD have to include all, including those with severe forms. Your cherry picking off one end of the spectrum, which makes it invalid.
No, we have no idea if our category of 'autism' is actually biologically meaningful. If we look at the known causes of autism (which together account for only a small minority of autistics), some of those conditions only cause low functioning autism, and some only higher functioning autism. So it's certainly plausible to think of a cause for HFA that isn't involved in LFA.
Your right, we don't know either way for the mass of people on the spectrum. They currently all however are linked diagnostically as possessing ASD and described as all being on one spectrum.
There may be subcategories, but right now only a very few fit into those, with rarer conditions. What the OP is suggesting is pure hypothesis and without any factual support. A common enough error, this fishing for superiority despite all evidence being to the contrary.
