Because dropping to Direct Law means that pilots who aren't used to manually trimming the thing outside of a simulator will have to very quickly get used to doing so in what is likely to already be a high-pressure situation.
Agreed that the workaround procedure is not ideal, but as I said before, and as the EAD clearly states, this workaround is temporary and only applies to a relatively small number of airframes.
