Yes, but it'll make Dublin a worse place. That's something local governments should keep in mind. Also, the top corporations OWN the governments worldwide at this point. The suggestion that any of this will significantly affect them is naive at best.
I don't disagree - I can't imagine Ireland signed onto this without getting a serious benefit from it... and I think that ideally we should be looking at solutions that don't require any individual country to be altruistic - but still, I'm happy the change has happened.
I think it's literally a case of it was getting done with or without the Irish government, so they took the "all members will have a minumum of at least 15%" to "all members will have a minimum of 15%" change so they had something to present as a win and to avoid a later discussion raising the minimum further.
