The point was not about pilots not having accelerometer derived speed data as part of IRS/INS but about the automatics completely relying on pitot tubes and not being redundant and using accelerometer calculated speed as backup. From engineering point of view, loss of Pitot tubes does not really require disconnecting the automation but someone somewhere made the decision (or formal regulations) that this is what is supposed to happen.
Someone has to make a decision here - either make the automatics more redundant or require the pilots to regularly practice without it.
