Your wishful thinking does not lead to the rejection of the multiverse hypothesis. It is not pure speculation, nor is significant evidence to justify a conclusion, yet.
There is no such thing as ultra ultra ultra fine tuning. Fine tuning is a hypothetical hypothesis to justify a Theist agenda.
Could you at least be honest? Fine tuning is not limited to Theism.
As for the multi-verse here is one scientist's view of that:
For a start, how is the existence of the other universes to be tested? To be sure, all cosmologists accept that there are some regions of the universe that lie beyond the reach of our telescopes, but somewhere on the slippery slope between that and the idea that there is an infinite number of universes, credibility reaches a limit. As one slips down that slope, more and more must be accepted on faith, and less and less is open to scientific verification. Extreme multiverse explanations are therefore reminiscent of theological discussions. Indeed, invoking an infinity of unseen universes to explain the unusual features of the one we do see is just as ad hoc as invoking an unseen Creator. The multiverse theory may be dressed up in scientific language, but in essence it requires the same leap of faith.

Many physicists who talk about the multiverse, especially advocates of the
string landscape, do not care much about parallel universes per se. For them, objections to the multiverse as a concept are unimportant. Their theories live or die based on internal consistency and, one hopes, eventual laboratory testing.
As skeptical as I am, I think the contemplation of the multiverse is an excellent opportunity to reflect on the nature of science and on the ultimate nature of existence: why we are here.... In looking at this concept, we need an open mind, though not too open. It is a delicate path to tread. Parallel universes may or may not exist; the case is unproved. We are going to have to live with that uncertainty. Nothing is wrong with scientifically based philosophical speculation, which is what multiverse proposals are. But we should name it for what it is.

So what is it, I know and I am not a scientist. I know, the limit of knowledge as human behavior in this everyday world and I can spot both when someone claims knowledge using the word "science" or the word "God".
Here is a proponent of the multi-verse.
[A]n entire
ensemble is often much simpler than one of its members. This principle can be stated more formally using the notion of
algorithmic information content. The algorithmic information content in a number is, roughly speaking, the length of the shortest computer program that will produce that number as output. For example, consider the
set of all
integers. Which is simpler, the whole set or just one number? Naively, you might think that a single number is simpler, but the entire set can be generated by quite a trivial computer program, whereas a single number can be hugely long. Therefore, the whole set is actually simpler... (Similarly), the higher-level multiverses are simpler. Going from our universe to the Level I multiverse eliminates the need to specify
initial conditions, upgrading to Level II eliminates the need to specify
physical constants, and the Level IV multiverse eliminates the need to specify anything at all... A common feature of all four multiverse levels is that the simplest and arguably most elegant theory involves parallel universes by default. To deny the existence of those universes, one needs to complicate the theory by adding experimentally unsupported processes and ad hoc postulates:
finite space,
wave function collapse and ontological asymmetry.
Our judgment therefore comes down to which we find more wasteful and inelegant: many worlds or many words. Perhaps we will gradually get used to the weird ways of our cosmos and find its strangeness to be part of its charm.[59][73]
— Max Tegmark
Note the highlight. That comes down to an emotion, wasteful and aesthetics, inelegant. His whole argument rests in the end on what makes sense to him in his brain; i.e. it is subjective. No different that some theists. They share that the world must be as it makes sense to them individually and subjectively. BTW the quote from Max Tegmark is a case of fine tuning. He fine tunes the math and then declares that it must be so, because it doesn't make sense to him otherwise.
Some aspects of science are not really science for the everyday world, it is an odd mixture of philosophy and subjectivity.
So what is your answer? Remember I am a global skeptic and I have seen most versions of people confusing objective and subjective. You might have solved it, but I doubt it. The western myth of reason, logic(math) and evidence is that, a myth. It's actual falsification is of the theory of everything is that I can believe differently. So can everybody else. Everything includes subjectivity, but is not just subjective.
So:
Law of nature, in the
philosophy of science, a stated regularity in the relations or order of
phenomena in the world that holds, under a
stipulated set of conditions, either universally or in a stated proportion of instances. (The notion is distinct from that of a
natural law—i.e., a law of right or
justice supposedly derived from nature.) ...
Law of nature | logic
So here is a question: Can there be one law or combination of laws, which universally hold for all instances for all of the natural world and not just the physical parts?
And I just answer: No! That is the falsification of the psychology of some humans, whether they use science or religion. They believe in the same regularity, an universal one, which holds of all cases, thus it amounts to always a positive outcome even if only for all humans in the in the end moral sense and I just answer with the negative: No!
Now you are off The Baha'i Faith, so you want good for humans. Well, in practice that amounts to a combination of limited cognitive, moral and cultural relativism. And no matter how nice you do it, I don't fall for the Laws of Nature always ending up with a positive outcome. I am a skeptic, so the negative is my line of work.
