Agree with that alright, though if a ground is full, it looks better! (Thinking United Park here, or even Belfield if Bohs are in town! Finn Park is a dump but looked great v. Dundalk too)
Problem is, such an exclusion could be a vicious circle. If we get ignored (I know nobody really cares about us, but ignore that fact!), we're going to fall behind the big four Dublin teams in terms of exposure, and our crowds aren't going to increase, and we're not going to get money to improve our ground. This could help the big clubs break further away, which nobody wants.
I think games have to be announced two or three weeks in advance at least, to give both sets of fans time to try and make the game look as good as possible. For example, more time means more time to sort out away buses, get word around the locality, get new flags, etc.
