Of course you can check - I agree. My point is an estimate of dates is more useful directly if you are not staying within Egyptology, as it allows clearer comparison with other middle eastern civilisations at the time.If I'm reading a very old article on Egyptology, and it refers to something taking place during the early 18th dynasty, a quick check on Wikipedia would satisfy my curiosity as to what time period the author was referring to.
If, however, the author had followed your advice and given the estimated year instead, I would be misled, since while "18th dynasty" has remained unchanged in meaning, being an arbitrary label of convenience, estimates as to when the 18th dynasty actually ruled Egypt have evolved over the years. The jargon here is a useful aid to understanding, precisely because it is unambiguous.
If you are staying in Egypt it makes little difference. Old Kingdom, Middle Kingdom, New Kingdom equally - good for pure Egyptologists perhaps, but a shorthand that does not help for comparative history as much as estimated dates.
When cross refencing records a universal term - like a date - is very useful.
