Even if it weren't. The parable of the wedding had guest that were invited. The banquet had already been prepared and so the Master ordered that others be 'compelled' to come. All who didn't come, didn't want to. Many who came didn't want to either. I think the answer does not have to be an unlimited atonement, but a 'sufficient' atonement. For me, it is more meaningful to say God has all the available resources 'should' all have chosen to come. Nobody would have been left out. It is God's desire that no one should perish. What we then are arguing, is the 'means' of how He keeps that concern and it is no poor thing to simply say "He died for you too, come in." Rather, for me, is to say "come, who cares if your plate was meant for another, it's free! Come!" In that sense, I don't think this particular argument is that much of a big deal. I realize many do, but I'm convinced "God loves you and has a plan for your life" is gospel. "Christ saved to save sinners, of which you are a part" is gospel. Whether or not Jesus would have died if I were the only one isn't something that my ego needs to answer. I am simply grateful and can't go much beyond that. I'm humbled that God loves us, in our fallen state, at all. We are terrible to one another, to Him, to animals, to His world, etc. etc. No, I'm not a mass-murderer but I certainly hadn't done much to make His world a better place.
