Why would you want to equivocate on the notion of 'existence' like that? Why not just use the term 'universe' or 'world' to denote all there is?
I don't really care for your use of 'finite' and 'infinite' or the entire structure of your argument. Whatever...I think I know at the end of the day what you are trying to say. One objection that comes to my mind is the following:
You take it to be that case that if X is 'infinite' (that's according to your own usage of that word -- so here, it means that X is temporally without beginning or end), then it follows that X is 'uncaused' or otherwise not reliant on causation. That's false. Consider a Hume-like objection where X is an infinite set of contingent entities, in which each contingent entity is explained by other contingent entities, and collective explanation of all the parts constitutes explanation of the whole. That's an example of some thing that is both 'infinite' (in your sense of the word) and yet "reliant on causation".
Do you understand my objection?
Note here that I am not saying that such an explanation would satisfy all strong versions of the principle of sufficient reason because I don't think it would: it would fail to explain one brute fact, namely that there are and always have been contingent entities. But what I am saying is that there is definitely something wrong with your move from 3) to 5) (your 4) makes no sense, and even if it did it would be extraneous).
