And that is exactly what almost all airlines do, including BA.
When you buy a flight on BA's website the fares displayed are the total cost of each flight, including all taxes, fees and charges. Nothing is added on between that point and finally paying for it, but a breakdown of the taxes, fees and charges included in the fare is available via a simple link if you wish to see one.
I still fail to see your point.
