But you can still hand-write any word you can spell, right? If you really try? Imagine trying to write on a whiteboard and just being completely unable to remember how to write "shoulder".

There's a big difference of degree here.

If by handwriting, you mean "painting" then yes, but only because there are so few letters and they are relatively simple.

I am Danish, and we have three letters that are not from the Roman alphabet. I constantly have to think about how to paint æ.

Even writing e.g. "frimaerke" is not unintelligible, though. One could also imagine that ø and æ were replaced by the more common ö and ä in the future.

I think the "there are so few letters and they are relatively simple" is the point here.

I suppose you inadvertently illustrated the problem...
