Every bus shelter contains maps and timetables for every route. The maps are of the general area and show other bus routes.
It is simply not possible to show every stop on a map because they are too close together. The average distance between bus stops in Dublin is around 250m. But the details are on the route maps on the website as has been pointed out to you.
I have travelled in many cities in the UK, Europe and the US and have never seen a tourist bus map where every bus stop is marked.
Here's a tourist map of bus routes in central London. Only the major interchanges are marked - not every stop.

And here's the Dublin Bus city centre routes with major stops marked.

Both simple to read and understand in conjunction with a tourist map. Last time I was in London, I had a pop-up guide with three maps - tourist map, Tube and bus maps. Simple to read and understand. Same in on recent trips to Paris, Prague and Budapest. The same maps exist for Dublin.
If Dublin Bus were to produce a route map with every bus stop marked have you any idea of the size it would be given how large the city and network is? I'll give you a clue - it won't fit in your pocket.
Despite all the information that has been about what exists now and is planned into the near future, you keep ignoring it and nit-picking for things that are not done elsewhere for obvious reasons.
