I think it could also be related to Czech Republic being the #1 country in terms of beer consumption per capita [1]. It's definitely a national drink there.
To be fair there are many tourists coming to Prague just to drink. And we usually drink low-alcohol beer, 10 degree beer has ~3% alcohol content. And finally hard alcohol is less popular.
Actual alcohol consumption is not that high. But yes, in pub water is often more expensive than beer.
