I agree with you on both points.
There are plenty of gays in Dublin. It's a capital city of well over a million people which draws in gayers from all over the island (including Belfast, Cork, Galways etc etc) and always has done. It has more non-nationals coming in from overseas to work than ever and tons of tourists.
Dublin's night life woes have never been down to just one issue. It's a mix of our licencing laws, the cost of those licences and venues, and the late/ stunted development of a proper club culture here. In recent years the fact that a lot of 30 and 40 something gays are screwed by their mortgages doesn't exactly help either!
Anyways it's good to see someone trying something new and somewhere new so good luck to them!
