So, instead of a 'right to' free speech, rather we _would_ have no laws restricting freedom of speech (libel and incitement excepted). This was the understanding that would've permeated Parliament, the courts, the palace, and the hearts and minds of everyone who understood it.

This is optimistic ahistorical nonsense; the UK had a censorship regime until the Lady Chatterly trial. There has been intelligence service related censorship as long as those have existed, as well (see Spycatcher, Zircon). And let's not get into Northern Ireland.
